This morning I took my daughter to school and when we got to the front of the school she got out and I drove away. I looked over and the passenger side door light was on and thought she had played with it and left it in the on mode, but I noticed all the interior lights were on. I removed and checked both door button pins and they go in and out smoothly and lights are still on. Pulled the interior light delay relay and they still wont turn off. Thinking I can manually turn all off and look into it this weekend when I realized that the small square red lights at the ends of the doors are still on when I closed the doors.

If I pull the #7 fuse they all turn off, but this fuse also controls the "Diagnostic Control". Any help would be appreciated

I know this is stupid...

But I had the same problem and discovered that my rear hatch - which seemed to be tightly shut - wasn't quite.

Make sure the rear hatch is completely shut.

Sounds like a bad ground. Wally Plumley has a good writeup, so you may want to search on his name and "interior lights". From what you're describing, a ground wire is loose behind the interior lights. I would start by checking the passenger door light since it was last closed (and possibly jarred loose) when you noticed the problem. I think the most common place to have a problem, though, is the dome light between the sun visors. Pop the light out, clean the contacts and make sure they are all in place and not rubbing any other metal. Do it to each interior light untilt he problem goes away.

RELAY RELAY RELAY ....the 86.5 > all have a time delay relay it holds on the lights for about 30 seconds perhaps your's has forgotten how to count ... next to last bottom row right next to the double relay part # 928 618 225 01 .

Thanks, but when I pulled the relay out they still stayed on. I will look into bad ground next.

The lights are wire Hot all the time so when the ground grounds the light comes on ...so maybe one of the grond wires on a light is grounding to the body ? that is all the pin switches do is touch a ground wire to the body BUT the ground signal from door switches goes through the relay. Look at the rear hatch reciever pin switch on the bottom there are two wires brown and brown with white stripe try unplugging them.

Diagnostic control power is not needed unless you have a diagnostic tester connected... so as a temp solution this iS OK.

One of your Brown white wires to the light fixtures is probably shorted to ground (or the fixture is broken) - take each fixture out to check, if any lights don't work check those first). It could be that you have a brown/white (switched ground) wire connection swapped to the light fixture frame connection (so did you mess with any recently?) Also first check the connection at the very bottom of the hatch receiver (behind tool panel) - is the switch broken or the wire shorted to ground - test by pulling the wire off

I haven't had interior lights for 10 years now since mine would not turn off. Looking at this thread, I went out and checked my hatch switch by pushing the plunger down manually with end of hammer and sure enough, that switch was intermittently turning the lights off. I tried to clean it and adjust it but just decided to disconnect that switch (disconnect the two wire connector) to the so that it is always off. The doors now control the lights on and off. The hatch does not turn the interior lights on or off but who cares as my doors now turn the lights on and off. There is a timer on my 1988 so takes about 15 seconds or so for the lights to go out when I shut the doors. I can live with this setup as I now have interior lights. Thanks for all the hints on this thread.

And thank you for posting! I've been searching & troubleshooting the same problem - the hatch switch is the culprit.
