Hello everyone. I have a 1997 SL 500 with auto climate control. BAir is cold but I am losing blower activity , comes on for a minute or two then nothing. All other a/c funtions seem normal. I think I narrowed it down to the blower regulator. I solid state sealed control piece mounted to the top of the blower motor.

Where is the best place to purchase ? Part number is a Behr # W0133-1597985 list is around 500.00 clams.

Any suggestions?
