First off thanks in advance for the help. Just bought a 1986 740 Turbo at a police auction. Got it for $1200, was that a good price? Car is in great shape everything works. I noticed that a few fuses are missing. Most cars have empty spots. Where can I get a diagram of the fuses and relays? Also the heater/AC controls dont seem to be working. When switching from AC to floor or defroster vents its doesnt change, only comes out on the floor. Any ideas where to start on this one? Also there is a switch on the dash next to the fog lights that looks like a Y, what the heck is that?
Thanks

Wiring Diagrams I can help you get from Alldatapro.com, unless other members have differnet sites without login. I believe your A/C diverter door is stuck to one position so it wont direct to other vents. Other complaints no idea.!

 

There is also Valves under the hood that go bad and not allow Vaccum to get to the climate system.

The switch you are asking about should be for the power antenna.

Also the Ashtray should have the fuse info on the back of it.
