87 e30 a/c aux fan

[algee101]

Does anyone know where the high and low speed switches are located for the aux fan. I am not getting any power to the aux fan and both relays are good and the a/c is working. Help..

The fan switch is on the top left (driver's) side of the radiator. There's also a resistor behind the front bumper. If the resistor's bad, the fan no worky even if the switch is good.

thanks i saw that switch but for some reasion i thought it was only for the coolent system..i jumped the switch and the fan engaged.

Make sure it works on both speeds. I think it defaults to high speed if the resistor is bad. That was the problem I had.
