Radiator fan question

[zanelord]

Hi all, long time BMW owner but first time posting here.

Currently own a 2001 325i. Having a mechanic put in a new radiator fan/motor/shroud assembly. I know, should've done it myself but other work had to be done it and they normally do a good job so I left it for them.

My question is about the connections. Mechanic tells me there's only 2 wires coming off the fan (from the motor I'm assuming), but that there are 3 lines that need to be connected. He told me he thinks the 3rd cable is probably for a switch. The parts aren't from the dealer, bought it online for cheaper from a place that said it was OEM. Looking at my Haynes manual though it shows a timer unit on the back with 2 cables connected to the central motor, and 3 running connected on the other side. So my question is: is there anything wrong with the new part, or do the connections just need to be made inside the timer unit? Any advice or further explaination would be appreciated.

the proper objective in repair should be to return EVERYTHING the way it was in it's original state. trying remedy/jimmy the wrong part to fit is pretty much a thing of the past. It will only result in a WOMBAT situation(waste of money, brains, and time).

better you source out the correct parts, or return and exchange for the correct parts if you have to.

I don't think there is a better way than that. Esp when you work with electrics.

^^ I agree. What about the fan that was taken off the car? How many wires were coming out of that one?

You got the wrong part.

There should be 3 wires coming off the fan; and 3 on the harness coming to it: ground, low speed and high speed.
