FSU or climate control unit

1363 Views 2 Replies 2 Participants Last post by  dimitrym
My 2002 E53 climate control unit is dead and the fan keeps blowing when the car is off. Can that be because of bad FSU / FSR or should I get myself ready to shell out $600 for a new control unit? Is there a way to check that before I buy the parts?

Sound like two problems the way you describe it:
1. Dead control unit.
2. Defective FSR that keeps the fan blowing after you switch off.
I would change out the FSR first and see if the fan switches off when it should then move on to the control unit. (Always eliminate the cheapest suspect part first).
That's what I thought too. Thanks!
