Wierd sound 2005 Focus ZX4 SE

Asked by Feb 02, 2012 at 07:40 PM about the 2005 Ford Focus ZX4 SE

Question type: Maintenance & Repair

Ok, here's one for ya! when my heater fan switch is on you here what sounds like a switch or solenoid clicking on and off, and then a whirring sound. When I was driving and at park I couldn't figure it out. Then I turned off the heater blower and it stopped. Turned it back on and it started. don't know what it is, and doesn't seem to be affecting anything. I recently replaced the alternator , but it was doing this before that. Only thing wonky now is my ac doesn't blow cold, but hasn't for a while. Then again, this noise has been going on for awhile. any ideas guys?
