I recentley purchased my first Mercedes, it is a 1994 S500. Unfortunately I have a couple of issues with it. The blower motor for the Heat/AC does not work. I bench tested the motor and it operates fine. The regulator I'm not sure about. Is there a way to test that component to ensure that it is the cause of the problem. Also can someone tell me how that regulator works. It appears that it provides the ground for the motor, maybe through some resistors, i'm not sure unless iI have some kind of wiring diagram on it.

any advice or help will be greatlt appreciated.

Thanks !!!
