Question about GMC Envoy
I recently replaced the clutch fan on a 2009 gmc Envoy but the vehicle is still making the same noise as before I changed out the clutch fan - does anyone have any ideas on what else the problem could be.
Check the A/C Cluch . This is a common problem on today's Cars .
If that is not it , It is most likely your Idler pulley for the Serpentine Belt , once they get some miles on them or a little dirt they start to be trouble . Hope this helps!!! Grant

Work for GM dealership.The fan can be replaced anytime and a pcm reflash can also be done anytime.If the service engine soon lamp is on because of cooling fan code it is broke!!!!! As far as the price sounds about right

could be wrong here but sure sounds like its out of fluid at the "master cylinder" look near the brake master cylinder for a seperate little container for the clutch. bleeding is tricky because it is small and wants to run out of fluid quick. you have to keep adding each time you bleed. Hope I helped. Thanks

Yes,it is the blower resister,it controls all the speeds to the blower motor,it is located near the blower motor,and it might have a wire harness that is burned up too,replace it,and the wire harness,and the blower motor,the blower motor is what causes the resister to fail,it draws too many amps,even though it might sound good,and run fine,it is requiring to many amps to run it.If this was at all helpful,please rate,thank you.

Sounds like you may have disconnected the battery. Does the rough idle only happen when the defroster or A/C is on? If so clean your throttle body with throttle body cleaner with the battery disconnected. When finished, drive it for 5 or so miles with the defroster / AC off to let the computer relearn the settings. This will solve your problem.
