Heater blower conundrum on my 911 SC with a 964 motor. 12 years ago, i pulled the relay and touched nothing else. Today with major help from my friend Brandon Steffenhauser I re-installed a blower, plugged in the relay on the rear fuse panel and tried to hook up the motor to the wiring harness.

The harness has no power, even with the levers pulled up in the cockpit. Fuses are good, the rear fuse gets power with the key on.....any suggestion on where to start trouble shooting?

Would like to get the switch to activate the blower when the levers are pulled up....

Bad relay or corroded relay socket. Just for fun, hot wire the motor and make sure it spins.

Yes it does. I have it wired to a keyed fuse in the engine bay panel.

Get some tiny wire brushes or a small dremel brush and clean out the relay socket.

Hey pal, this ain't 911 world.
