Mercedes® 240D Blower Motor, 1982-1983 (123)

The blower motor provides that cool blast of air from the A/C vents in the hot summertime and it can be miserable if your blower motor fails. If your A/C compressor comes on when you turn the A/C and you do not have air blowing through the vents, the problem is most likely the blower motor. NOTE: A simple check for the blower is to use a voltmeter and see if the blower is receiving current.. If the blower is receiving the proper current and isn't working, the blower is the problem. If current is not reaching the blower, then the problem is further upstream in the climate control system, such as the pushbuttons.
