1999 Cherokee -Since I've bought my latest XJ this past spring (4th to date), I've been knocking items off my 'wish list'. The next item I'd like to tackle is adding a Delayed Shutoff for my head lights. I've been lucky so far with a few other electrical related items as the wiring harness connection points for 'Cruise Control' and under dash 'Courtesy Lights' were there (tough to locate, but there). I do not believe my vehicle had a head light delay feature as it had a standard dome light (since replaced), and was built as a Police Vehicle.


How difficult would it be to add the delay? Hopefully, it would be as simple as just adding a module, and a fuse or two???


As always, any advice is appreciated.

I thought all '99 XJ's had the Headlamp Delay Module. Looking at the wiring diagram it shows no special feature for police vehicles.

Maybe your module is inop.

Easy to test, start car, turn on headlights, shut off car, turn off headlights after engine is off. Go look at headlights.

Funny, really though .... Headlamp delay works that way....
Shut off lights before the engine - lights go out.
Shut off lights after engine is off - lights stay on for however many seconds.
All Canadian vehicles past IIRC mid 90's have it, much like DRL's ... Can't remember if it's a module (like DRL's) or a part of the PCM programming though.

Just checked it again without any luck. Not sure what to do next. I continue to research it. Let me know if anyone has any ideas what i should be looking for.

Yep. That's the way my 2000 works.

I don't know how many times I've accidentally triggered the delay in a parking lot and had someone tell me, "Hey, you left your lights on!"

The headlamp delay modle looks like this:

And, that is the part number.

It's located near the headlamp switch. You'll have to remove the trim panel and knee blocker from under the steering column to get at it.

So if the Delay Module is there, then it may simply need replacing?

CCKen

I would think so.

The fuse that protects that circuit also protect other circuits so if it was blown those other headlamp circuits would be inop also.

I'm pretty certain that on mine, they will only stay on if I open the door and THEN turn the switch off...

Sounds like your Heep is busted mang. Delay module is supposed to keep them powered if the headlights are switched off after the ignition.

Yup... For about the first month of having my 99, I always had to go back and check, or wait for them to shut off. And yeah I always get the "Hey, you left your lights on" I think it'd be cooler if they shut off when you locked it with the remote

CCKen,
Thank you, i will hopefully have time to dig into it over the weekend. It may be a week or two, but i'll let you know how i make out.
