Turn signals/lights acting up

Okay guys...

1- when I turn on my lights my drivers fender signal and my passenger grill turn signal dont come on... I tap the fender and the grille and they come right on no problems. I am thinking that this is a bad ground?

2- When I hit the brakes my driver's side rear light cuts out completely. (I checked the bulb, it looks fine)

3- When I try to use the driver's turn signal... nothing... when I use the passenger signal... it works but is real slow to blink...

Any ideas?!?!?!?!

I agree!

The giveaway is in your #2 statement, when trying to use the brake light circuit it causes a previously working function to cease. This is the "signature" of a faulty ground. The higher amp circuit is "looking" for a place to get to ground. It overpowers & "back-feeds" through a lower amp circuit.

There is no situation that cannot be improved with a small but well-placed explosive.

Now both my turn signals work when the lights are off. As soon as I but my lights on the left will freeze up and not blink, but the right works regardless. I still have the issue with the drivers side brake and reverse light.

I had my utility trailer behind my jeep... plugged it in and the left signal seemed to work. I am going to assume that it was because my trailer's wiring harness has a good ground. Where are the rear grounds on the jeep? Could I tap into the ground wire (which one?) and just make a new ground somewhere?

The rear light's ground is the bolts holding it to the tub. Take em out and clean everything up well. Put them back in snug and see what happens.

Check the rear bulbs by swapping left to right and see if it works.

Ayup... I took the mounting screws to the wire wheel on the bench grinder and I had to take a small wire brush to the metal plate in the back of my tail light... works fine now! Thanks fellas!
