Hello and Moin! I’ve been driving a Volvo 850 that I used to buy with 340tkm. I’m incredibly disturbed by the non-functioning fan of the interior ventilation and I’d be happy to fix the problem because the permanent humidity inside the car and the view just don’t do well! By the way, the car has an automatic climate control. I’ve read a lot here and acted accordingly. A small crash: – At first the blower didn’t run at all. – The blower engine, however, ran perfectly in the extended condition. – I’ve replaced the pre-resistance with another used one, because I suspected the error in this one. – Now the blower motor (in built-in condition) ran for about 2 seconds when I switched on the ignition. After that was quiet again. – So I could assume once that the old pre-resistance was broken or was smoked by another malfunction function. – So I’ve got a used control part, because I’ve always suspected the error. – I’ve installed it today and unfortunately, the operating part of the operating engine didn’t start again.
