- - 300TD A/C problem (http://www.peachparts.com/shopforum/showthread.php?t=4405)

My '85 300TD can't seem to keep the cabin temp right. Blows hot when hot, cold when cold, and random inbetween. Shop has replaced the control unit, I know that the setting is sensitive, but set it at about 22C and it can be stiffling or fridged. Anyone have similar problem...and a solution?

Be sure the tube to the aspirator is in tact and the motor is running. Also most of the 123's had a control unit called the temperatureregualtor. It is behind the glove box and can cause the problem you described.
