This sucks, my electical skills are pretty good and I can't even figure this one out. My left blinker doesn't work when the parking lights are on. THe left blinker on dash stays lit. All bulbs are good, flasher is good, checked my wires and they to are good. WHAT ELSE!!!!!!
 

Hi,

I think I mentioned this in another post but...

What is happening is as follows: you have a ground fault in that part of the electrical system. The front light bulbs have two filaments, one bright one for the turn signal, and one dimmer one for the parking light. When the ground is bad, the power you apply to one of the bulb's filaments will find the path of next-least resistance which is to back feed through the other filament's circuit.

Therefore, with no ground, turning on the parking lights makes the power back feed through the turn signal filament, then through the dash blinker indicator filament, then to ground.

You'll probably notice that when the parking lights and blinker are on simultaniously, things really go crazy, this is because both filaments now have power, and there is no ground and no where for the current to backfeed.

Check the bulb sockets, the grounding prong is probably corroded and/or broken off. Also check bulbs themselves and the ground wires from all the turn signal bulb sockets to the chassis and be sure they are making a connection.

I know the above scenario sound alittle strange, but it has happened to me twice now on my cherokee :mrgreen: :roll: :mrgreen:

Good luck

Hey Nick, or anybody else. The front left fender blinker is very dim. Does it mean that the ground problem is near there. I cant find where that fender blinker is grounded. Oh yeah the connector looks ok. I hope i can find it soon. This is pissing me off!
 
OH WHAT A RELIEF! I found the problem. It was the front left bulb (never "seemed to be a problem") The connector that is on the bulb is a little wobbley. Thanks Nick!
 

My TJ will do the "quick blink" or the "solid light" indicator from time to time when it is wet. Mine started happening when when I put Euro Guards on my tail lights. Also, mine will switch side LOL sometimes on the Driver and sometimes the Pass. Kind of Fickle I figured it was just a "Jeep thing" ;)
 
Hows this for weird. Sometimes my left signal indicator will come on solid, but the lights will be off. I just barely touch the switch and it will go back off. I figure its corrosion in the dash or something from being rained in.
