I have a 1982 380 sl and was wondering if anybody can guide me in the right direction. My blower motor motor stopped working and the heater seems to be circulating warm air from the vents the motor is not working but air from the outside is still blowing warm air in where should I check to see if the motor is still good and possibly just a relay if anybody has an image of the relay i would have to look for that would be much appreciated thanks
