My A/C has been blowing out the defroster vents, then the floor, then finally after about 10-15 miles down the road it will blow out the A/C vents. I have taken it to countless mechanics without success. Finally to Ford Motor CO. The part alone without labor is $905. I opted not to do that. The bad thing is every time I turn off engine and then restart - I have to go through the entire routine of blowing out defroster, floor, etc. |
