    Hey everyone! I'm desperately in need of some help.. I purchased a 2002 525i about a year ago, the freon just went out a couple months ago. Being the "handy man" my husband is, we made the mistake of putting in "A/C Pro Ultra Synthetic R-134 Refrigerant". The AC worked GREAT for a couple days...

    When you first turn the ac on, are both of the fans (auxilary fan has two fans on it right?, not refering to the fan blades connected to the fan clutch) supposed to turn on? or just the one on the passenger side untill the engine becomes really hot and then both fans turn on? 97 540i 166k miles
