Electric Cooling Fan
Well, same problem on my 99 328i ... isolated to the control module on fan. First, given my lack of experience I would have to say pulling the fan wan't quite a piece of cake for me. The age of the car and the brittleness of parts makes removal of the front bumber a bit difficult. Also, the Bentley manual has a few errors or what I would call omissions - such as arrows not showing ALL the right locations for things. Also, the point about the rivet-screws, well I well be darned if I could get all six of those removed- only one came off in one piece the rest were destroyed . . surely a better method could be engineered for this simple and inexpensive part.
The control module on the fan can be further disassembled, removed and the clear rubber componet facing removed - - I am now in the process of checking what part failed on the circuit board. It seems ridiculous that the entire fan assembly and shroud must be replaced just for the control module, especially give the high cost for the entire assembly. Hopefully, my diagnostics on the circuit board will reveal a simple failure that can be replaced by something off-the-shelf perhaps at Radio-Shack otherwise I guess I will have to bite the bullet and go the expensive route.
