Hi Guys,
Can't seem to figure out whats going on. It's a 1990 model and the windows and sunroof just stopped working. Fuse is ok and tested good but I replaced it anyway. Does the window control under the seat operate the sunroof as well? I noticed after buying the car that if my wife and I went to put the windows down at the same time one would stop. Something is amiss.

Yes, on your MY there is a Power Window/Sunroof Control Unit. I am unfamiliar with debugging window/sunroof issue(s) that have this control unit. Others will be chime in.

Just throwing some old threads here. Maybe you'll find a pearl somewhere that'll help.

Do you hear a faint clicking from under your seat when you are pressing the window or sunroof buttons?
Have you tried to lock the car from the outside (driver side) and close the windows with the key from the outside?
Edit: BTW yes, the little black box controlls the sunroof too.

Yes I've pulled the controller out and can hear the relays clicking when I press the window and roof buttons. Just can't work out why I only have 2.6V where it should be 12V. Don't even know where to begin to look.

take the controller box apart,
put deoxit 100 on the contacts,
let the box sit for a few hours, also put deoxit on the fuses,
and then try the unit

You did replace fuse #31 correct? check that you get 12V+on the bottom fuse terminal, probe into the open dimple on the body down to the fuse blade with it still in place

Ok, have 12V at the bottom of the fuse. I should add that the car has had an alarm fitted and remote central locking. The PO said he has never had an issue with it. It was installed by Bruce Buchanan.

Are we not thinking RELAY at all here gentlemen?
Nevermind.
I answered my own question after I posted. There doesn't appear to be a relay for the sunroof and windows as there is in the earlier cars.
