Hello fellow MB enthusiasts,
Im new here . I have a very nice 1981 380sl and have developed a fan blower problem . The automatic climate control high and low speed fan selections will not work in the heat mode but will work when the AC switch is turned on only . The fan also works when the defrost or bi-level positions are selected .If I go from the defrost or bi-level selections back to the high or low speed fan selections in the heat mode , they will blow for a short while and then quit never to come back on .Can anyone tell me what part needs replaced and where it is located ?
Kind Regards, Otto
