When I brought my S500 the previous owner said that the blower motor was shot. I replaced the motor and it was fine.[:@] Turns out that I need a blower motor regulator for a 1994 S500 but I now have two blower motors, one of which I obviously don't need. [:-]I am willing to trade the blower motor for a regulator or sell it outright. Bottom line is that I need a regulator. Anybody got a regulator that they are willing to trade or sell at a reasonable price??
