This is right from GMC service repair manual Odometer The vehicle odometer is calculated and stored electronically in the instrument panel cluster (IPC). The base IPC contains a season odometer and a trip odometer. The uplevel IPC contains a season odometer and two trip odometers. Momentarily press the trip/reset switch on the IPC in order to toggle between the season odometer and the trip odometer. Press the trip/reset switch for greater than 2 seconds, while the trip odometer is displayed, in order to reset the trip odometer. The IPC calculates the mileage based on the vehicle speed signal circuit from the engine control module (ECM). The odometer will display 'error' if an internal IPC memory failure is detected. The odometer displays either miles or kilometers as requested by the activation of the Personalization button on the steering wheel controls.

I don't know

loose connection or you are overloading outlets,if your trying to draw more than 15 amps continiously i'd reccomend fused wiring back to battery or main fuse box

Have you changed the filter and fluid lately. Check your service manual to see how often that needs to be done.

Reset airbag light ????? Light on ,problem with the system , DTC'S - diagnostic trouble codes set in air bag control module . Have the codes diagnosed ,fix the problem an the light will reset it's self . Your best bet ,take your vehicle to a qualified repair shop.

2004 Envoy xuv 6 cyl when I turn on the A/C the truck stalls but as long as I keep my foot on the gas it will continue to run

U need to remove the door's inside panel and reattach the mechanism that controls the door lock.

just the solenoids need attention they are add- ons for the transmission and the transmission is ok

Need to remove inner panel and check the gears. You can also disconnected the motor so your battery won't drain.

In my opinion, it's almost certainly the radio. Even when turned off, it is still alive managing a few other things (like chimes) until you exit the vehicle, and I suspect that part of the radio is faulty.

door skin is the metal part of door --door panel is usually removed to access the inner workings --remove the panel screws and pry gently to release the clips and panel comes off

The regulator is bad possibly . Have to take the panel off the end gate to check it . Endgate Power Window System Components The endgate power window system consists of the following components: • Endgate window switch • Endgate key cylinder switch • Endgate window interior emergency switch • 4th button of the key fob • Power roof switch • Endgate window regulator • Endgate module • Power roof module • Endgate regulator 30-amp circuit breaker If you hear the motor run ,has to be a problem with the regulator . Removal Procedure Swing the endgate open. Remove the regulator bolt access plugs (3). Remove the endgate trim panel. Refer to Endgate Trim Panel Replacement . Remove the endgate inner panel reinforcement. Refer to Endgate Inner Panel Reinforcement Replacement . Remove the endgate window. Refer to Endgate Window Replacement . Remove the bolt (3) retaining the regulator to the endgate. Loosen the nuts (1) retaining the regulator rails to the endgate. Remove the regulator by sliding the regulator side rails up and out of the keyhole slots (2) in the gate. You mite find a video on youtube on how to do this job.

Rob, when the battery is disconnected for any reason a couple of things happen, and frankly it's a design error on the GMT360 platform (Envoy/Trailblazer). Your mechanic did not make an error here. Issue #2, your vent actuators blew out when the battery was re-connected back up, it happens, it's common. Issue # 1 is a little more complicated. The flashing light means misfire, is a seperate issue and a coincidence. Pull the codes out with a scanner and report back, may be bad coil pack, happens and is common. Idle problem and starting to die is an easy fix, betting it only happens when the AC or defrost is on. Disconnect fuse #10 and #28 under the hood. Remove the throttle body and clean it with a sensor safe spray like Seafoam. Drive it around for the computer to relearn the newly cleaned throttle body. Idle problem will be fixed.

You're in the GMC Envoy section, but could be very similar, as I know Envoy, Jimmy, Blazer, Trailblazer are close to the same. Yes removal of the door panel is easiest. The electrical connector from the mirror should plug in at the door master switch. The mirrors typically only have 3 nuts to take off, very simple. I have cheated and not removed the door skin, just peeled the plastic back enough to get in there.

Before you replace the #46 HDM relay (in the fuse block under the hood) try exchanging it with the #45 cooling fan relay and see if your low beam lights work. If they do, the HDM relay (actually solid state module, not a relay) is bad.

This is usually a connector issue. If the connector terminals are not fully in the connector, they will connect better when warmer. Remove the TPS connector and look at the terminals on the female side. Push all of the wires into the TPS connector to see if one is not in fully. Also check for bent pins on the male side.

test and check the headlight switch -wiring , connections and sockets for power
