Tail lights flashing!!!!! Help!
 

When I turn my lights on at night my right signal turns on and stays on as if it's suck and also with the head lights off and I turn the right Signal on the tail lights flash as well as the signal and the dash board lights. I was wondering if anyone could provide so information on where to start to fix this problem. Thanks

It's a 1996 ford ranger

Sounds like your turn signal relay is going or gone. If it's not that it's the steering stock itself.

i had similar wonky issues - trace your trailer harness back and see if you find a worn thru spot like i did. Mine was way back like directly left of the spare tire it rubbed thru (how and on what? no friggin idea)

i assume the bulbs are good? under normal circumstances if the turn signal rapid flashes you got a turn signal fillament burnt out. If the indicator stays steady you got a parking light fillament out. neither should make the dash lights blink but the turn signal wiring backfeeding into the park circuit would...

Yes, trailer wiring first, it can get corroded and cause shorts
