Does anyone know for sure if there was a recall on the Aux. Fan Resistor. In a 1990 300ce Mercedes Benz? I took my car to a shop nearby, after this resistor became firery red hot. And burn some nearby wiring setting them a fire. At the shop the mechanic pulled up some info on that Aux. Fan Resistor, and told me that it was a recall on that part. But when I called the dealer and they pull in my vin#. They said that there wasn't a recall on that part. Someone please help. Also is there an air intake system that I can pull in my car to increase horsepower? Or what can I do to correct the sluggishness in my car? Please and thank you.
