Question about 2002 GMC Sierra

1 Answer

AC and controls no operating

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?

My 1990 GMC Sierra runs hot when ac is on


Check the radiator fan to make sure it is turning at full speed. Could be a bad fan-clutch.

2005 gmc sierra heater fan quit working. I lost the fifth speed months ago and a couple of days ago lost the other four, the first day the fan would come on sometimes while driving then quit after a while...


1-4 speed are the blower motor resister . It controls all 1-4 speeds, also it's under the passanger side dash around fan, the 5th speed runs off a fuse the is located in the fuse box. It's one of those square fuses , not the relays but fuses. The resister will run $15 and fuse $5 . Good luck. I have replace these before

2000 gmc sierra 2500 the engine temp rises when stopped. It has a 6.0 V8 i also noticed the transmission temperature is going above 200degrees, thats never happened even hauling loads in texas heat


Just guessing but, I'd say either fan clutch is going bad, not turning as fast as it should be once temps go up or if you have electric fans, either fans or relays bad. I'm leaning more toward the fan clutch. The fins on the impeller of the waterpump can also wear done over time and reduce the amount of water flow.You may also want to make sure the fins in the radiator are clean and not stopping air flow. I'm assuming that when you're moving there's no problem so that should say that water pump, thermostat are doing good. Please rate this. Thanks

AC is cold, then hot..


you need the tempature blend door motor. My 01 silverado had this issue about 1 1/2 years before i was tired of messing with it they are not hard to replace. The cover (if it is still on) for passenger side floor ducts needs to be removed and the motor is near the right side of "hump" (trans tunnel) mounted horisontial with the armature pointing upwards.
