Re: Engine sqeals when front defogger is turned on.
Sounds like the ac compressor may be locked up when defroster is turned on..there is a disconnect by the ac ompressor pulley that can be unplugged and the belt should turn free..defrost will work but need to check the compressor before its needed in summer..replace if needed..
