"intermittent wiper" function lost
« on: December 9, 2009, 05:40:38 PM »
A few nights ago it was drizzling, so I had the intermittent wipers in my '84 RC set to the minimum wipe interval. I forgot to turn the wipers to "off" when I parked outside.  Overnight the temperature dropped below freezing.  In the morning, I started my RC and noticed the wipers try to move but they were frozen to the windshield with a thin layer of ice.  I freed the wipers and they work fine in the low and high settings but I've lost the "intermittent" settings.

What happened to my intermittent settings?

    Do they work at all on intermediate? or do they work as if you just have them on low.
    Mine act weird on delay only whene it is real cold in the morning, they just keep on wiping as if they are on low, i think it is the relay and sounds as if that may be your problem as well.

    does that same thing go for an 83 w150? mine works as if its on low, but i had mine out and when i plugged it back in it sounded like it arc'd but i never saw a spark, it works but as if its on low? could i have burnt the switch or do i have a relay? hopefully its the relay cause the only place i can get a switch is threw the dodge dealer for about 80 bucks

    My wipers work fine on the low and high settings but the delay function is lost.  If I slide the wiper switch just past off, the wipers immediately enter the usual low range and just stay that way till I slide the wiper switch all the way to the high setting, at which time they go into the high mode.

    Everything worked fine prior to the incident described in my first post above.

    On an unrelated note, my RC was one of the Mopars of the Month for November at mydodgetruck.com and 440magnum.com:

    Thanks, DODGEBOYS and jha79.  I'll get a new wiper relay and install it.

    Do you think that having the wipers stuck to the windshield with ice and having the wiper switch inadvertently on the intermittent setting when I turned my RC on fried the relay?  Or was it just a coincidence?

    I hope that it solves your PR's problem as well, pjnuts19!


    Anybody have a part number or source for these?

    The part number may be stamped on the part or try #4222060. These were used from approx early 80's into the early 90's on both cars and trucks. If you want new I can give you some sources.
    If you have no time to answer the questions or try the advice then don't expect to fix it anytime soon!

    Chump;

    Yup, I need some sources for a new one.  

    The part # you supplied is correct and is stamped on the side of the green box (intermittent wiper control).  The part's discontinued by Mopar and NAPA, Autozone, and Advance have been of no help.

    Thanks!

    NOS and Used... www.arizonaparts.com $40 or $15 plus shipping

    Cheapest shipping usual gets my business. I have dealt with both with good results. The old guy at Arizona Parts can be a bit fussy but we expect that from most NOS dealers.

    Is this a correct replacement for a '88 Ramcharger ?

    According to  http://www.collectorsautosupply.com/search.asp , the 4222060 is a 81-84 and the 4312002 is a 84-85.


    My '88 Power Ram parts book from Chrysler lists the 4222060 as the correct control for the '88 RC and PR.

    4312002 is for different models like the Caravan and some cars...it appears it is wired different at the connector. You need to stick with 4222060.

    4312002 has a much cheaper List Price and I would assume that it is paired up with a wiper motor that has been redesigned to be more cost effective.
    Also sometimes using the info on the web at the parts sites is NOT the most reliable. I've been dabbling in parts and wiring for about 40 years and I try to be as reliable as possible. :):)

    Today i've found again my original wiper "box", lost since i replaced it with the green 4222060. This used green box was bought from a US vendor with other Ramcharger parts.

    The original * didn't work at all (i had only one wiper speed) and its cover was damaged.
    But i coudn't give its #because it was lost ... until today !!
    It's a grey box and it's ... 4312 002 (07807) !!!

    * I don't know if it was put on the car at the factory, it's the unit i found on the car 2 months ago.

    Well, I'm still waiting for my intermittent wiper relay to arrive, and I've not touched the wiring or other wiper components, but, as of yesterday, when I turn the wiper switch to the OFF position the wipers stop immediately.  They don't return to the "down" position like they did before.  Is this also related to my loss of "intermittent/delay" function (as described in my first post at the top) or is it a different problem, possibly invovling the wiper motor?

    Received today the "box" 4312 002 bought on Ebay (at 6.95 $ !!). Works perfectly.

    I made an error with references, the one i had since 2 months was a "black" box 4503 104 and not a "green" box. This wipe control works only with non-intermittent speeds.

    Hi - so 4312002 was wired the same (at the connector) as the green 4222060?
    Still working well for you?
    My intermittent function is not working either, it is P/N 4503104

    Thanks.

    Did you have to remove the dash to replace it?

    I can see the unit under the dash but cant see how it is attached.

    Tried both a new 4312002 u it as well as a NOS 4222060 unit.
    Both have the same issue - wiper works in low speed when the wiper switch is in both the "off" position and the "low" position.

    Wiper works at high speed in the "high" position.

    The existing box on the truck is the 4503104 u it tht works correctly in low an high, but dead in the delay positions.

    Add an extra ground to the wiper motor housing.  I've found that the timers are very sensitive to weak grounds of the motor.

    It may as simple as loosening and retightening the bolts holding the motor down.

    This is an excellent idea even on the standard wiper motors.  I find the factory ground strap to be weak and easily corroded and/or broken.

    Just added an additional ground strap.
    Wiper still only works in low and high, no intermittent delay.

    there are different intermittent wiper modules, not sure how they differ internally, but you mentioned that one part number that worked properly, that is likely the one that you need to use, as the others are designed to work with a different wiring harness, or under different voltage requirements.

    The 4503104 was on the truck when I bought it but the delay function never worked.
    I bought the other two part numbers but they were always on when the switch was off.

    For whatever reason, Mopar in it's wisdom uses the same plug for a lot of these wiper timers.  BUT they are wiried differently. You might be able to swap some by swapping terminals in the plug but you would need wiring diagrams for both setups.

    Any other insights into this issue? At my wits end.

    on my 85 I have low high and the intermed sticks and wipes away for a while, you hear the relay clicking in the dash some times..

    i tried a couple of the green wiper delay relays and I get different results.

    what I have found tearing into the wiper motor is it has fingers with point contacts and a round disc turn under them like a washing machine timer of sorts.

    anyway..the 3 or 4 wiper problems I have solved with the delay not working is to replace the wiper motor, the stock ones can be opened to find the broken contacts in side.

    there is also different plug in pieces that goes on the motors, all moter are not delay motors but a 2 speed only,with the piece on motor matching the delay relay box...when the wrong motr is used with a delay switch and delay relay you get it to park but not work in delay mode but have low and high speed.

    napa had the new replacment wiper motors for delay mode for about 80$.

    I have not run across a bad dash switch or a delay relay myself , it is the motor point contacts everytime so far for me.

    I have a 2 speed motor on my 85 harnes with delay, no worky in the delay mode but has low and high...it does park when you move to OFF mode. (waiting on funds to replace it)

    same thing with them not parking but delay,low/high speeds work, points in the motor head again.

    I did not read all of the post but did see you are at the end of the rope...maybe this might help out.

    Thanks; any pointers on a part number for the delay motor?

    My w150 is an '81, but has the inside controls from an '88...

     not off hand, but they look it up for the yr make of the truck with or with out delay.

    you want the plug in piece on the motor(looks like a black sqaure box thing pluged into the motor..and this is the motr that lays on the firwall not sticks straight out from firewall.

    I agree with adding the ground strap also, never hurts.

    Here's the motor assembly on my truck can't make out what type it is- does it look like the correct one for intermittent function?

    In the 80's, and 90's, they only had one wiper motor for both delay, and non delay. So if it fits, its the right motor.

    So I need the black box that bolts to the motor to be changed?
    Could there be a different intermittent wiper arm needed?

    The black box on the motor, is just a terminal cover. The wiper delay box, is mounted under the dash near the steering column.

     I would put my bet on the wiper switch.

    test and error was my only way to fugure it out. i changed switch/relay and then changed motor for fix

    the others I just went right to a motr swap for the fix.

    not saying the switch or relay does not go bad on them, I was told the the termanals under the black box thing on the motor do make a differance.. could be only 1 motor for  2 speed and delay 2 speed.

    i have a spare relay and switch if you want them. PM if you do.

    I will post a pic of mine tonight, point to what I am talking about,I have a couple moters on the shelf and you can see the differance I am talk about..

    In the 80's, and 90's, they only had one wiper motor for both delay, and non delay. So if it fits, its the right motor.
    Not too nitpick but there were at least two different styles, there was one prior to 85 or so, that was taller than longer and then they changed in 85 or 6 to the style he shows in his pics, I need the earlier style for my truck cause my intermittent does not work either and I am using an earlier harness.

    They both use the same bolt pattern
    My name is Jason Anderson, I am an avid collector of early Dodge Brother/ Graham Brother car/ Truck literature. Have anything to trade or sell?

    I have 77, 80 and an 1986 factory service manual and am getting better at using them :)

    I am owned by a  1986 big block 440 N.P 435 4 speed 4 wheel drive short W.B truck and some of his pals

    Thanks for showing an interest in my truck :)

    The black box on the motor, is just a terminal cover. The wiper delay box, is mounted under the dash near the steering column.

     I would put my bet on the wiper switch.

    after looking at them tonight in hand, the black box and the thin piece are called impulse bars, they tell the motor what to do via the points riding on the wheel inside housing.

    i think you have to match the correct relay under dash to the correct impulse bar on the wiper motor,

    this one i removed the cover from was gave to me and was supposed to have worked on delay, but I notice the impulse bar does not match my 85 square impulse bar which works on delay but stick and has run away for a while then un-sticks and delays...or they just stick and wipre steady for the long haul on delay mode.

    the points fingers are not broke on this one, the greese is dry and caked up some but a little moving and re-lubing the gears with it is moistined right back up and should be good to go now. (mopar greese is the bestest greese)

    you can see the circles where the finges ride on the wheel, and the contacs look good. ( i have seen them burnt and broke off)

    here are some pics, the motor with no impulse bar should be the standerd 2 speed wiper, the skinny impulse bar motor may need a specific relay?  the square box impulse bar goes with the green relay in the pic.

    i just pulled my 85 harness and it has this same relay as the 85 harness i have as a spare, both had the square box impulse bar on the motor.

    looking at the 2 motors i have, i agree they seem to be the same motor, just has a differt cover and wire hook up for delay than a standerd 2 speed motor.

    I would also make a small ground strap to go from this ground screw on cover to ground strap on wiper motor mounting bolt, then a ground wire to the VR bolt and then to the engine block. i also run a ground wire from wiper motor ground strap to ground screw of wirehaness on the firewall and then to -side of BATT term for a good ground.

    also run a ground from the -side of BATT to square metal box thing screwed to inside of dash that has the ground wires hooked to for the dash switch/lights ground, the key buzzer and wiper delay relay are both on this square metal dash grounding box.

    never can have too many ground wires IMHO.

    here are pics to study.

    yea,capaciitor... thats it...dealer showed it as a impulse bar and are indeed different..maybe he was meaning the radio suppression.

    so any motor with a impulse bar should work for delay/low/high and the one i pictured with out an impulse bar is a standerd 2 speed....correct?

    got me? I would not have thought the wiper motor would have radio suppression capaciters on it, I thought that would be the condincer looking thing on the intake and hooked to the coil was for radio suppression.

    like i said, a new moter aleays fixed my troubles with 3-4 trucks and the delay wiper not working.

    changed switches/relays a few time before replacing the motor. {noclue}

    Got it :-)

    I have a radio suppression capacitor on the ignition coil as well..

    Hopefully a new motor will come with everything needed, cover, capacitor etc etc :-)

    the ones i got at napa did, they bolt on and the stock plug plugs in.

    I also have a wiper motor from a 92 DAK that will bolt to the d-150 truck but plug is different IIRC, I did cut it for a splice job if I ever tried to wire it in..

    it is a little smaller and does not have any impulse bar to it...but it was a delay wiper truck I pulled it from.

    not sure if it can be made to work...junk for future projects someday.. or hammer on the bench stress relief. LOL!
