Wj Assitance Needed (2002 WJ)

Last night noticed the interior lights stayed on in the WJ after hitting the lock on the remote, noticed locks worked but no "beep".



Got back in and drove it and interior light wouldn't go out. Interior light eventually went out after parked and locked (after a couple minutes), still no "beep".



Today started looking at the situation and found the outside temperature gauge (in overhead cluster) shows "- -". After trying other things, found electric windows won't work on any of the doors. Locks work (lock/unlock), mirror controls work.Then found the headlights don't work on Auto (it was getting dark, lights didn't come on. The info center correctly showed driver/passenger doors ajar when opened, but not the rear doors.



All this happened in the last 24 hours. Checked all the fuses and they all read good. Checked to see if all the connectors to the back of the fuse block were tight.



Where are all these gremlins coming from?

I'll defer to those more expert than I, when they jump on, but it sounds like a Body Control Module issue to me. It could also be impacted by a Drivers Door Module or a Passengers Door module as well. The functions that are causing problems route through the BCM, but many through the door modules as well. Take a look at the wiring diagram to start your diagnostics and pay particular attention to your grounds.

There's at least one broken wire inside the rubber boot between your driver side door and door jamb. Start your repair by pulling that boot back from the door and checking for broken wires. It's a tight area to work, but it's also a common failure point for our WJs.

I hope this helps you, buddy!

Yes. BCM or a door switch sticking/failing somewhere has been the consensus here in the forum over the years. Removing bulbs or replacing them with low current draw LEDs can help with battery drain issues until you can get it sorted out.

Rage! Rage against the dying of the Jeep.

Check driver and passenger wiring harness boots for breaks, that's generally the most common cause of the issues you're experiencing. A fried module is the second most common cause. Unplug one and then the other to see if your gauge issues go away. Replace if so. The fried module is generally a symptom of a different issue, though, and not necessarily the cause. Check the C200/C106 block behind the passenger kick panel for corrosion or arcing varnish from excessive pin wipe.
