The wires that feed my blower motor regulator are fried at the connector on the firewall. The car is a W124. I pulled the blower motor and it works but there is no power to the regulator on any wire. I tested the blower motor out of the car with a battery charger. Itraced back to the connector on the firewall and that connection if fried. Also I don't have cruise control. In all fairness I just purchased this car and the cruise never worked or the blower motor. Any suggestions?
