WANTED ISO "Facelift" blower motor regulator 124-821-21-51 (with cabin filter)
- Thread starter winmutt

Tons near by, none have the right year/model. The one that does had the blower motor yanked within 2 days of landing at the lot. The SKP I bought off rock auto was a dud. I have a pre facelift one on route but at this point and looking for alternatives.
I don't know what else to think. Its an SKP. Tested motor on bench and it works fine. I get 12v at the plug on the firewall on red and ~3v on yellow. I tried shorting blue motor wire to ground with red hooked up and no love. Any other suggestions? I sourced a used motor and regulator and also have a pre facelift new regulator on the way.
Did the fan die completely, as in zero speed? Not just a fixed and/or low speed only?
If the fan is dead and the motor is good, you may not have current flowing at the red wire from the firewall... could be enough to show +12v on the meter, but not enough to run the fan. There were recent posts about this IIRC?

Check the power from the red wire going to the motor/regulator with a test light. You could see 12v with a multi-meter but there still might not be enough current to run the motor. If this is the case, it could be a bad ignition switch. I went through this and posted about it here:

Any load, even a light bulb, may suffice. Or apply a larger load (like the fan) and check for voltage with a meter/VOM when the load is applied. If you read 12v with no load and it drops to zero with a load applied, there's a fault somewhere upstream - likely either the fuse, OR the ignition switch, per Jon's adventure posted above.
