Mercedes 190E auxiliary fan issue - fans will only work with the air conditioner on?
Please help. I have a 1993 Mercedes Benz 190E. It has had it's fair share of issues over the years, and the past 5 months I have put more money into it than the car is worth, one problem after another. The latest was a new radiator, heater core that blew apart, entire bracket structure behind front grill fell apart, etc etc. Point is, after the new radiator was replaced, then all the radiator hoses went, and finally all seemed fine...for awhile. Then the car kept visibly overheating, radiator needle pushing 100 Turns out, the auxiliary fans behind the front grill are not "kicking on" when the y shoud at a certain temperature. Thought it was the fan relay switch, but that is new also, plus the fans do work, but only with the air conditioner running? Pulled out the blue temperature sensor and the fans went on? Put the sensor back in a minute later, and fans kicked off!! I had all three sensors replaced, stilll the car will just overheat and the fans will not go on no matter how hot the engine gets!! In order to avoid blowing a head gasket, I have to keep the air conditioner on the entire time I drive the car!! I drve 40 minutes each way to work, and the car eats gas anyway because the oil ends up burning into the gas itself (another problem but do not want to spend thousands more on the car). So, that is my problem...I have to drive with the a/c on at all times! If I don't, the auxiliary fans will never go on at all. This is crazy! Also had fuses checked and replaced. Please, any help or advice?? Am spending over $22 a day in gas because of this issue. PLUS, new issue too as of 3 days ago...entire car is vibrating when it is on, when driven, constant vibrating and sounds ike a turbo jet ready fo rtakeoff. Do I need a new fuel filter? New air filter? No idea!! BUT my prmary concern is the fact that I have to keep the a?c on just so that the car doesn't get to hot! Please respond, thank you.
