I have no turn signals or brake lights on my 1990 Dodge Ram Charger. . 
I have checked the bulbs, fuses, don't know what else it could be besides the wiriing. .

STOP

Before you tear anything apart. . .

Triple check and make sure the hazard switch is pulled out (off).  I haven't had this on my RC, but on other dodge vehicles from the 80's the hazards are on a flasher of their own and when activated, the turn signals and brake lights are deactivated.

Hey, the same thing happens to mine sometimes. im not sure what it is but they go out, then start working seemingly without any rhyme or reason. Good luck, Josh

If the RC is equipted with an "multifunction switch", this could be the culprit,they are easy to disassemble. They are printed circuits with electric grease as a lube, and over the years this dries up and messes up the functions of the sw. I have had two of them, that the blinkers would not work properly sometimes and that affects the tail lights, also. I found this out after months of trouble shooting the blinkers and tail lights. My wifes 96 Dodge van had the same problem with her wipers (part of the MF SW)

If the MF SW is the Problem, remove it from steering coloum, dissassemble it ,and clean it with "Electronic Cleaner", (not brake cleaner), regrease the contacts on the printed circuits, with a good synthetic grease, and reassemble. This process worked on my two RCs, and my wifes van.

If all else fails check the MF SW out. They are easy to fix. New ones from Mopar are (I think), $150.00
They are the same for many years.

Hope this helps

I just recently went through this in my 79 RC and it turned out that the lug on the bottom of the fuse panel that powers the turn signals, brake lights, and interior dome light was shorting out intermittently across another wire.  It is a pain to see as the panel on the early RCs is up in the top of the dash and this is all underneath it.  I had to use a mirror to see it.  Once I moved wires around, the problem went away.

howdy and all is good , the way to do it is ask your question [ new post ] but use this post as reference by either cut=copy=paste or a link to it saying that it helped solve your problem or you have the same problem , its the masters that run the place that want it that way
