Instrument cluster erratic warning lights, gauges stop working.
This is a common problem with an easy fix. If you are experiencing weird behavior from the instrument cluster it quite possibly is caused by corrosion on the circuit board on the back on the instrument cluster. To fix this you need to remove the instrument cluster. Refer to YouTube for this there are lots of videos shopping this, This step is much easier than it sounds, there are 4 screws and one plug. Inspect the circuit board you should see about a dozen places that have a dusty/crusty appearance (see the attached image). Clean the corrosion using isopropyl alcohol and a cotton swabs. Reinstall the cluster and your good to go.

2004 GMC Envoy XUV SLT
There is a technical service bulletin regarding this problem with 2004 GMC envoy. Actually there are 3 separate issues with regards to the elecronic tailgate. The reason why the dealers are backordered is the part you want keeps failing after a time of being installed.
For the particular problem you have of the electronic latch not working, the bulletin recommends a inspection of the endgate connector C900. Look for the wires to be backed out of the connector or not properly crimped. To crimp you will need a crimping tool available at any electrical supply shop. The connectors can be had from the dealers.
The other solution referred to intermittent operation of the endgate but can apply in your situation also. For that, look for chaffing at the wire harness connectors for the endgate actuators located at the upper right and lower left latches. They have been found to be pinched up to 8 inches away from the actuators. In this situation it would be ideal to replace the connectors and install in a way so wires will not be pinched.
The other thing to look out for is dusty sensors. For this you will need to remove the tailgate trim panel and locate the 2 optical sensors on either side. You can feel them with your hand, they will be the size of a nickel. Clean all the dust under the trim. In addition to that you should open the switch and use contact cleaner to clean out any dust or debris inside there. There is no mechanical way to open the door once the electronic side has malfunctioned without damaging the door. I hope this helps.

2004 gmc envoy window won't go up rear wiper obstruction
I know this question is old, but I am responding so others with the same problem can see. I wired the Rear Window Motor Park Signal wire and the Rear Window
Motor Speed Signal wire together and it completely bypassed the rear
wiper motor. Now the window goes up and down. This doesn't fix the rear wiper motor, but you will be able to have access to it now that the window is out of the way
I made and album to show.

2004 envoy xuv tailgate problems
I also have a 2004 GMC XUV. My gate would go down but not swing open. In trying to fix it, the gate then refused to go to the flat position.I have removed the cover plate on the gate and found the one of the
solenoids loose from its mounting. Resetting the computer by disconnecting both battery leads and holding them together for ten seconds worked to restore function to the gate going flat, but the swing still does not work. I believe it is a bad solenoid or motor for the bottem left latch pin.
