My headlights won't shut off on my 97 jeep grand cherokee. I have pulled the relay and they still stay on, don't think it is the switch because it still turns on and off the tail lights. Any ideas?

I'm going to post this in the clarification section. I don't have a wiring diagram for a 96 Grand Cherokee headlight circuit.
The 95 models used a circuit breaker built-into the headlight switch. The 97 models used a fuse in the fuse box. If your model uses the headlight circuit breaker, a short in one of the headlights or the wiring harness would trip the circuit breaker in the switch. You could unplug one headlight at a time to see if it continues to go on and off.

pull the relay for the daytime running lights if they go out, then your relay is stuck in the connect position.

You check the fuel pressure while the engine is running or cranking if it won't start.Should not go up or down drastically.Should stay within 10 lbs. variance. don-ohio

The relay on our 1999 Jeep Grand Cherokee was located behind the headlight on the passenger side of the vehicle. technicians at the Jeep dealership that you have to remove the bumper to get to it OR you can remove the headlight assembly and drill a hole large enough to get a socket and extension to the bolts on the relay..removed the headlight and drilled a 5/8" hole to get to the relay screws.
Why Jeep puts this relay in such a hard place to reach is beside me - - - other than perhaps they don't want it to be easily customer replaceable. Argh! Good luck.

check fuses and relay

U got a BURNED LiGHT SWiTCH, usually they have plastic inside the contactor that selects the switch from dipping/high and turns on ur LiGHTS!
Replace the whole LIGHT SWITCH assembly!
Hope that might help u out!

did you figure out what the problem was? Mine is doing the same thing and I think it is drainning the battery.

bad headlight relay or switch or a short

have you disconnected the actual switch and see what happens

Only 2 things can cause this either the headlight switch or the headlight relay,chances are it's the switch,if you have a multimeter pull the relay out and probe the leads with the headlights in the off position you should only have power on 1 wire,with them on 2 wires are hot if this is the case then the relay is stuck,it's in the fuse box under the hood,another thing can cause this if the fog lights have been rewired to stay on even with highbeams on,power will feed back to the headlight circuit.
