I have a 87 4.0l 5 speed truck, it has this odd quirk. If I have the headlights on, I can not turn them off if the truck is off, I have to roll the key to the on position then back off again for them to turn off. the dash shuts off but the headlights stay on..... Anyone heard of this? maybe is it supposed to be that way, my other truck is a 89 4.0l auto and it doesn't do this.

 

Its normal i beleive, just try it some time and see how long the lights stay on...i think they will go out in a couple of min.

 

DON'T LEAVE THE LIGHTS ON! Mine does this all the time. Just kill the lights before shutting the engine off. If you forget, which I'll admit I do quite often, just switch the ignition to "on" and back to "off" and the headlights should go out. It takes less than a second. Make sure all switches are off before shutting the engine off, simple as that. I left mine on one day, in 10 minutes the battery went dead. We don't have a fancy timer to kill the lights on our old ones.

 

Even if the switch is hit when the engine is off, the lights will stay on. At that point you do the ignition thing. Better than leaving them on and learning the hard way IMO.

 

My 88 had a delay for the headlights and so does my 90. The lights should turn off after like 2 min.

 

its a safety feature... its suppose to light your way in the dark if you can't see they should turn off in about 2-3 mins... its a head light delay..

 

Sentinel headlights operate this way.

Key on, turn headlights off, they go off.
Key off, turn headlights off, they stay on for about 2 minutes.

 

I would like to add,that yes mine delay as well '90 cherokee nice feature for sure.

 

I have a 1998 Jeep Grand Cherokee v8 5.2 liter when I start the car the whole front vibrates and when I give it gas it in vibrate the even more that's in park or drive. what is the problem in how do I fix it. My contact info Meek247ram@gmail.com, asap please help

 

Good morning meek. You have a ZJ, not an XJ, are in a thread about headlights, and probably should have a few more cups of coffee before posting.

 

Hahaha, oh cruiser. Move this to another thread Meek. It should be in with the ZJ stuff. We're all XJ guys here. Good luck!

 

I honestly don't think mine has the delay thingy. Unless it just broke a long time ago and my dad never got to fixing it. For as long as I've had it I don't think mine shut off, haha. I don't wanna test it and find out the hard way either. I just make sure I turn them off before I shut the ignition off

 

Had the same problem with my-90 XJ. First few years the delay relay worked but then I got the same problem. Drained the battey. Solution was to remove the delay box and carry a flashlight in XJ for use when needed.

 

 

LMAO ! Wake up sleepy head ! Mine does the same thing (delay) it's normal .
