Thanks for your feedback. I actual problem with the gear shifter not letting the suv out of park is because the gear shift solenoid is not working. I had to take the gear floor housing off the car gear box in order to locate the solenoid. not and easy job removing the middle armrest house that includes the rear heater duct and floor gear shifter. Now you can see and disconnect the electric circut connectors, one for the gear shifter, and one for the rear heater controls. Then remove the gear shifter support bracket and lift up on the gear cable so that you can unscrew the push button gear shift solenoid. You know that is the problem because once you press that buttom the gear lever moves out of park and into drive, reverse, or nautural. KEEP THE EMERGENCY BRAKE ON.
Auto parts stores did not have the part so I had to per order it for $ 100. and 2 days to deliver to the dealer service department and I have to pick it up. Looked online but could not find a match so I had to pay way more than expected, plus down time waiting for the part.
I took pictures and tried uploading them to this comment, however, its not working for me, help ???So far it took 2 hours to disassemble and hopefully 1 hour to install once I get the part. Need various screw drivers, rachet with extension, light, allen rench, and star shape allen rench . In order to get the armrest and rear heater housing off, you need to find the small screws hidden under the cup holders and cd holder. Have a pencil magnet handy to catch small screws that may fall. Do not pry off the armrest, look for the all the screws.. (about 8 and then 4 holding the solenoid in place.

SOURCE: check engine light on - 2003 gmc envoy XL

That code represents a lower than expected reading for temperature (coolant). First thing to do is check your coolant level, as if it is low, then the sensor can not read correctly. Second, you may have a thermostat that is stuck open, allowing the coolant to cool off too much. The sensor should be mounted on top of the engine, near the thermostat housing.

SOURCE: need fuse box diagram 2002 gmc envoy

If I remember correctly if you look at the back side of the fuse cover, it should tell you what the fuses are. Also in the owners manual in the index, under fuses, it should give you a diagram of the fuse location for the acc. outlets. Good luck. The fuse should be a 20 or 25A fuse.

What does Fuel Level Sensor A Circut High Input for a 2004 GMC Envoy


The fuel level sensor is in the gas tank, and if it needs to be replaced, the tank must be removed from the truck.
