A/C & Power seat Problems

[Mark Davis]

I have a 1985 911 and the A/C blower and the power seats stopped working. I have check the fuses and they are fine I have replaced the relay in the smugglers box. Any ideas on what else I can check.

Thanks

Mark

The AC Switch and the Seat Switch check under the seat first and check power.

Mark,
Let's leave out the seat for the moment, they just add weight to the car.

On the evaporator blower you can test the circuit front to back or visaversa: here is a hyperlink in PP that will guide you:

I won't say this schematic is 100% but it is helpful.

Hint: start at the fan (direct power 12vdc off the battery with a jumper to the red/white spade terminal in the plug)

Thanks for the infomation I was able to jump it and the fan works. It turns out that the PO had run a new power wire for this and it had a burt out inline fuse.

Thanks for the help
