I have a 1987 Carrera with the auto heat knob and the two red heater levers between the seats. The blower motor had been running whenever key was on (regardless of lever position)– it had been that way since I bought the car 3 years ago – I actually thought it was supposed to be that way, until recently.

Last week the blower started making a lot of noise, so I took it apart and the motor had chewed up the front bushing, so the shaft was wobbling badly and the squirrel cage was rubbing and making the noise. I got a new high-temp bronze bushing seated it in the housing, slapped it all back together and everything was good. Motor was quiet and running like before – always.

I figured the motor wore prematurely because of the “constant-on” condition, so I searched on here for why, and went into the controls between the seats to fix the little switch in there. I fiddled around with it a bit and got the motor to no longer run whenever the key is on.

The problem is – now the motor doesn’t run at all! Never! The footwell blowers do run as they should, when I turn on the dash switch. I tried turning the auto heat up, I tried bypassing the switch altogether, but nothing works. I checked the fuses in the engine bay and they are all good. I checked and there is no power going to the blower motor now when the switch is ‘on’. I’ve not messed with the relay at all, but figure it ran before so that shouldn’t be a factor.
Any ideas?
