2003 GMC Envoy Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2003 GMC Envoy

The fuel level sensor in the fuel tank may fail causing erratic fuel gauge operation. Our technicians tell us that on high mileage vehicles you may wish to replace the complete fuel pump module assembly if this condition occurs.

On certain 2005 - 2007 vehicles, General Motors has provided a special service policy covering the fuel level sensor, agreeing to pay 50% of the repair cost. This coverage extends for 10 years or 120,000 miles from the original "in service" date of the vehicle. Please contact your local GM dealer for more information.

On vehicles equipped with rear air springs, the air compressor may fail causing the rear suspension to sit low.

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.

I LOVE my Envoy! I bought it new and it now has 112,000 miles on it, and I have had zero troubles with it. It's had 2 head lights and 1 tail light changed out. Heating and AC are perfect, and it still has the original brakes (and I live in the mountains!) It has great get-up-and-go. It's comfortable and roomy inside. Not the best gas mileage, I average about 18MPG, which isn't so bad living in ...
