Question about 1998 Jaguar XJ8L

1998 XJ8 Vanden Plas taillight problem

The taillights come on but go off after about 15 seconds. I found they stayed on if the headlight switch is in the "park" light position. However when I turned the key on and teh switch was in the park position the taillights and front park lights both went off after about 30 seconds. When the headlight switch was turned to the headlight position (or on auto mode) and the headlights came on the taillights went of after 15 seconds. I've heard electrical problems were available in the Jags, and now am inclined to believe it. I have no diagram to try to follow what happens when the switch is moved from one position to the other and what effect the key being in the on or off position has on the taillight system.
Thanks,
Rick

Check the electrical grounds for the taillights. In fact, get a diagram and check all the easily accessible grounds. Many of these are in the engine bay.

2004 Jaguar, Vaden Plaus,car just quit running going down the road. Had to have it towed home Won't start,turns over, just won't start,says Restricted Performance.


Sounds like it is some type of 'limp home' mode.
It could be anything. It might be as simple as a bad Fuel Pump Relay. When you turn the Key to the ON position (not Start) can you hear a little buzz for about 1 second? That would be your fuel pump running. You need to see if the engine is getting gas and spark.

Why when the ignition is off on my 99 Jeep Grand Cherokee do the headlights inadvertently come on & stay on for 10 to 30 seconds?


I used to leave my headlight switch in "Auto" mode - and found that after awhile, my headlights would do the same thing. I think there may have been some corrosion in the switch. I stopped using the "Auto" mode and this resolved the problem

Headlights taillights stay


it's running hot because of the battery. For example, some fuses are hot at all times, and some are hot manually with car running for instance. Try wiring the positive to a source that is hot only when the car is running.

Is the Wiring still disconnected from the switch?
If so, there is a contact of the Harness wiring when you left it loose. Not all models isolate accessory power suplies when the Ignition is switched off.

Xj8 instrument lights not on when headlights on


Make sure the dash lights aren't turned down first of all. I know that sounds basic, but I've seen it happen before. Believe the twist is near the knob to adjust the steering wheel which is lower steering column left hand side. Otherwise, I would check fuses to be sure. finally, the last thing I would do it pull the gauge cluster and check connections as well as bulbs.
