About a week ago, my ac blower just went dead..the lights were there but 0 airflow from the vents..I could make out the compressor switching on.
I was then told it was the Blower Regulator that was shot.
I'm having the same issue purchased two "OEM" regulators from Ebay from two different sources both just cause the blower to run a full speed even with the ignition turned off!!
Plugged blower back into original Behr regulator(9140010471) and stops blowing constant which works intermittent which is why I need to replace it, but at least I can stop the blower running.
Has anyone else had problems with these aftermarket regulators? I'm now looking for an original Behr regulator are there any differences or variations between the part number that would cause the blower to run constantly when replaced?
The only obvious thing I can see is the difference is the capacitors on the two regulators could this be the problem?
