Question about 2002 GMC Sierra
My GMC Sierra AC & controls have been going out at times for a year. Several days ago I noticed my fan was making a squeeling noise at lower speeds and my ac & controls would not work at all. My dealer charges $100. per hr. trying to find the problem. What should I look for?
Replace the BLOWER MOTOR RESISTOR this will allow your low through high controls to work again.. as far as the squealing sound oil the fan or replace it
just saved you 100.00 pleas return the favor with the highest rating
