Electrical problems

I need a little help here. my girlfriend has a 91 teg gs 5 speed. it has a few minor problems that i want to fix for her. the first problem is that the Rear Defrost switch seems to turn on and off on its own. sometimes it will come on and i cant turn it off, other times i want to turn it on and it will not. i am assuming that the switce is bad but i am not sure. second problem is the sunroof does not work i want to know where the relay and motor are for it so that i can fix it. and third is that the wipers are not working correctly. the delay does not work. only the low and high speeds do. on the teg what can cause? this is the dely switch in the wiper motor or is it in the car some where else? any help is welcome thanks.

I dont think very many people on these forums are electrically inclined....

yeah with this, your best bet is to get a haynes or one of the other manuals and look up the relays and whatnot. Also youd have a manual there to for the future projects.
