Why does the AC overheat the car engine and AC fan in engine compartment does not come on?

Asked by Jul 04, 2013 at 03:13 PM about the 2007 BMW 5 Series 530xi Sedan AWD

Question type: Maintenance & Repair

Engine overheats when driving in town with AC on.  AC fan in engine compartment does not kick in. Checked voltage at red wire on fan connection and got 13 volts so no fuse blown. AC also takes a while to get cold when you are first starting out and does not blow cool when sitting idling

If you have voltage on the fan it should come on. Sounds like it might be time to change the fan motor.

Your fan is not working properly will probably need to be replaced.
