I will say its one of two things.

 

1) a bad headlight switch

 

2) AND /OR a badly pinched wire loom.

 

You have to begin tracing. A couple questions.

 

Did this just start happening, or was it this way forever?

 

If it just started, what have you recently done. Been wheeling? Someone else use the vehicle? Has it been hit/ in fender bender?

 

There are a set of major wires, running around/behind the grill on the drivers side behind the bumper/brill. A good hit there can pinch/cut the harness there resulting in what you are evperiencing.

 

If no to any accident, I would get yourself a new headlight switch. These can be a bugger to change. There is a little button on the top that must be depressses to remove the center pin. Allowing you to remove the bpdy of the switch from under the dash.

If you haven't done this. I would recomend your aquireing the new switch before attempting removal of the old. That way you can see how the switch comes apart, before hand, once you reach in to remove switch, you have to feel your way, there is no room to see anything.

 

Good luck,

I had bad grounds in the sockets up front.

The simple test to see if that's it is this:

Take the bulb out.

Take the gasket off from the socket.

Jam a piece of stranded copper wire down that hole on the side. That's the ground part of the socket. once you take it apart you'll see why it's not a great design.

Worked the wire back and forth a few times to grind off the corrosion. A liberal application of contact cleaner may also help.

it's made so that when there's not bulb in there the ground disconnects, but it's very prone to corrosion.

I just left the piece of wire in there and it's been fine for me. just excersise more caustion when working with the front bulb sockets, as they now have a ground even with the bulb removed.

I had that problem too. The brake switch wasn't getting power. What I did was take the plug from the brake pedel and ran a new power line. That seems to be working for me. I am getting a little moisture around my fuse block cause some other fuses were wet and starting to rust. Let me know how it goes.

Do you have all of the right bulbs? I'd try just buying a couple of packages of new ones... There's no telling what a PO might have done. And make sure all of the bulbs are firmly locked in palce on the tailights. Mine were doing weird things last night because one of the bulbs got loose.

I had a bulb blow a week or so back. It was one of the tail lights. i took it appart and replaced both bulds with brandy new ones.

 

For the past week the marker light circut would blow the fuse after about ten minutes driving. It was strange, it would barely blow the fuse, I mean barely. Usually when a fuse blows, it burns up half of the visible metal inside. Not mine, it would be a tiny break, just enough to not make contact. I checked and re-checked everything!! I took everything back apart, cleaned and regreased all the sockets. I removed, cut and recrimped the ground leggs and reinstalled in new holes all with die electric grease for good measure. Problem was still there!! I was stumped! Then, during a phone conversation with my dear old dad. He reminded me of something, Just cause its new, dosen't mean its not the problem.

 

Guess what it was...a faulty bulb!!! I couldn't see anything wrong with it...but I went to a different store and bought new bulbs and re-installed them....and wallah...problems GONE!!!

 

You never know!!

 

Good luck,

i can't figure out why when i push the petal they won't come on....but when i pull the light switch out once..they come on...

i know they are supposed to but they come on BRIGHT so the stop lights and regular lights are coming on when i pull the switch..

plus when i push the lever to turn the turn signals on they don't even come on in the dash..i know the column is good its out of my cherokee

still stumped...

well i think i found that the stop lights don't come on when i pull the light switch out once...the stop lights just don't come on period...

 

I don't understand...the stop lights SHOULD'NT come on when you pull the switch???? Or was this just a typo? :oops:

 

Have you gotten your self a cheap tester w continuity? Have you tested the grounds to see if you have them everywhere? I am still saying the problem is either the pinched wires from the accident or the switch in combonation with a groin==und problem. These things are a PAIN to diaginose and take many hours to track down. Be dilligent and look carefully.

 

If you can't get a meter, get a couple long wires, run them directly to the batt and try to see if the lights will work with these wires as a test. IE you KNOW it will have a good ground this way and you can be positive of that once tested.

The grounds are the black wires that come off the plug for the blinkers. Have you tried the blinker fuse. It looks like a little can.It' located at your fuse black under the dash. If that has gone bad. There is one for your 4 ways and and blinkers. Does your 4 ways work? You could look in a Haynes manuel. They have wireing diagrams. Yahoo's group has some diagrams too.
