Hi guys! I have a 95 Jeep Cherokee Sport, and when it's cold or hot outside my headlights would always turn off, and back on again at any givin' time. Now that it's colder, they don't work at all, along with the turn signals. I look at my dash when this happens, and the high beam, and both turn signal arrows are lit up. The headlights, and both front turn signal/parking lights are off, but the back parking lights, and brake lights work fine.


I have changed the headlight pull switch, bulbs, fuses, relays- (for the headlights) and checked the grounds by the air filter box, and other plugs around it like I have read in other post, still nothing.


The only thing I haven't replaced is the turn/high beam leaver, and flasher relay, but I don't want to waste more money. I installed driving lights for now, and I manually flick the turn signal switch up and down so I can drive it... Does anyone have any ideas what it could be?

 

I went to replace my multi-function switch on my '93 Laredo when my headlights were acting up. Similar symptoms as yours. When I got in there to remove it, I found that the connector had worked loose and a wire had come out of it. The connector, or harness wires are sort of clamped together. Hard to explain, but you'd see it if you get in there. I took the new one back unopened. Been workin' fine ever since. Hope this helps.

 

Thanks, I'll try to look at the connections first and give an update.

 

Well, I took the high beam/turn signal/wiper/ switch out and replaced it with a new one...still nothing! I don't know what else to do. Maybe there is a relay I don't know about that may be the problem...

 

Get out the multimeter and test the connectors at the headlights.

 

Does anyone know what the wires under the driver side carpet are for? I think that may be the problem to my headlights, and turn signals. The floor pan is pretty well gone, and the wires are exposed to the weather. I think at one point I stomped on what was left of the floor and the headlights flickered, or maybe something under the dash vibrated. Any ideas?
