This has been going on for a while now,but it is now worrying me. Sometimes during the morning or when it is cold,I start the car and I can hear the blower squeeling like bad brake pads squeeling. Not the whole time but comes and goes, it fades in and out and happens for about 2 secs each time as well is very noticeable. This is beginning to worry me more and more. After I am out of the garage and drive out of the housing track or down the road it stops,even after I come to a light and stop. I do not hear it while driving just at idol and once again it stops after brief driving. I am wondering if anyone has experienced this before?
