90 camry power accessory problems

Does anyone know of anywhere that i can find some interior schematics for this car? My driver side control panel and seatbelt as well as the window buttons on all 4 doors stopped working a couple days ago. It isn't a fuse or disconnected harness and the passenger side lock button and seatbelt work fine. If anyone knows where I can find a diagram other than the shop manual or knows what the missing link that ties those things together is, your help would be greatly appreciated. Thanks.

I haven't done this in several years but I used to go to our local library and they had these large books (like 11x17 size pages) of complete wiring diagrams for practically all cars and trucks. You could take the book to the photo copier and several dollars later you'd have a complete set for your car. They were noncirculating books. Like I said I haven't had to do this yet for my current vehicles so I don't even know if they still have the books.

Check the wiring harness that flexes when the door opens for internal damage.

I went to the library to check but they didnt have a copy of the book I needed so I dropped a whopping 9 bucks on Amazon for it and figured out the problem. You were right Daniel it was a broken wire in the door jamb. If anyone is interested it was the white, red, and black wire coming off the smaller of the 2 relays that go through the door. It splits into two of the same wire going into the driver side master switch. Thanks for the help.
