1997 s500 Blower motor does not shut off when climate control is off
Blower motor does shut off with key. With the climate control on, i can control the speed and all seems to work as normal. I turn off the climate control and system switches to recirc and blower motor runs at about 3/4 speed.

Any ideas?
