Wierd sound 2005 Focus ZX4 SE
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?
