2009 GMC Envoy Problems

Loss of One or More HVAC Blower Motor Speeds

The HVAC blower motor may stop working at one or more speeds due to a faulty blower motor resistor block. Our technicians recommend to confirm the resistor is at fault by first checking the operation of the switch.

Check Engine Light Due to Gas Cap Issue

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

No Electrical Power to Interior of Vehicle

Electrical power may be lost to the interior of the vehicle due to a blown 125 amp fuse located at the under hood fuse box. This fuse can blow if jumper cables are connected incorrectly. Replacing the blown fuse will commonly correct this problem.

Check engine light comes on repeatedly. (1 answer)

I have taken the vehicle to 2 repair shops. When they look at the code it calls out "small leak" code. Replaced gas cap and this solved it for a few days. Reset light again and it returned in a few days. Also got "tighten fuel cap" message on dash.
