Customer Question

I have a 1986 300E Mercedes. Some one diagnosed that it needed the ac compressor as well as the blower replaced. It was done. Still there is a problem with the blower. I have to turn the ignition several times, sometimes six or seven, before the blower turns on. With the blower running the AC works fine. For the next few stops the blower comes back on when the engine is started first time. But if the car is not operated for say two hours I need to go through the same exercise again, turning the ignition six or more times to get the blower running. Without the blower working the driver's side and the passenger's side get very very hot. Can you help me with your expert advice though the car is not an Audi.

Hi, My name is ***** ***** for the delay.

I will do my best to assist you.

there are a couple of things that can cause this,,the most common being the blower motor resister,but,we have seen these automatic climate control modules go bad and cause a simuler problem.

try a new resister first
