The fan clutch will not engage. My lights have not came on as of yet. I can't afford to have the engine over heat. The part costs way to much. I believe if the envoy is doing this it should be a recall.

Check Engine Light illuminated and took the car to the dealer to have it checked. They ran a diagnostic test and said the Cooling Fan Clutch needed to be changed. Cost $1185.00. Outrageous! Read other same complaints about cooling fan clutch. With the number of complaints, shouldn't this be a recall also?

I have been experiencing the issue of the loud fan noise. It is extremely irritating and embarrassing, to say the least. I just I my thermostat and my O2 sensor replaced and I can't afford yet another repair. So very upsetting.tpearson512@aol.com
When I start my 2003 GMC Envoy, it the motor sounds like it is racing but I am not going more than 20 mph. The racing sound goes away sometime but it consistence. I have replaced the clutch fan but the racing sound did not go away. Any suggestions, I've been yelled at on neighbor streets as they hear my engine racing but I'm only going 20 mph.

I had many consistent problems with this car included ticking for at least 2 minutes near center of dash. The second time I'm hearing the sound of it getting louder when I am accelerating. Put a lot of money into repairs on this vehicle and it seems to be consistent with it's problems reoccurring.
