Sunroof, Windows and Locks Inop

[AirheadNut]

I have a 1990 HZJ81 with non-working sunroof and windows, and door locks that go crazy every once in a while. The sunroof is stuck open on the tilt position and it is getting wet inside, so any help would be appreciated! I’ve read a bunch of threads about this problem, and have checked all of the fuses in the panel and tested all the little relays in the RH kick panel. Is there anywhere else I should look for relays or fuses? Any other causes for this problem? I’m assuming that the sunroof motor is probably ok since the windows don’t work either.

You can manually operate the sunroof. If you remove the trim on the overhead switch you should see a large flat slot on the motor shaft that you can use a screwdriver to manually turn the motor until it closes.

Awesome, thanks! I’ll have to give that a go ASAP.

Well, I tried manually closing the sunroof, but the slot turned out to be a screw. If I turn it CCW it just unscrews, and if I turn it CW it tightens and then stops. The sunroof didn’t budge. Unless I’m looking at the wrong slot...

Any ideas are appriceated.

If you have the electrical wiring diagram book you can see where those systems share a common point of some sort. You might be able to find the pdf online.

Ah, looks like I have the 1990 FSM, got some troubleshooting to do!
