There's an emergency mechanical procedure in the Owner's Manual to unlatch it from the inside.

Then the typical problem is flexed wires breaking internally (inside the insulation) at the hinge line, inside a weather-resistant boot.

Also check rear fuse block fuse #3.

not sure what the manual says, but if you pop off that rear plastic piece, i think its all clips and one hex screw or regular screw forgot, anyway it will all become clear and you will be able to open it

Sorry, thought you wanted troubleshooting advice for a do-it-yourself fix. In that case, you need a trustworthy and competent mechanic.

the rods and such are quite self explanatory, i guess of course unless your lock selenoid or w/e, which will still be probably pretty self explanatory. I had everything out of the hatch, and the hatch off the car when i had to get it all re done after my trailer bounced up and shot thru my back window the second week i had the truck =[, either way if you can manage to get the plastic off, and take some pix someone can probably guide you through the necessary steps
AT LEAST you'll be able to open it for the time being, does the window OR the hatch work? either?

2005 Envoy XUV (Tailgate & Swing Gate not working)

After reading the posts in this thread I don't know mine is is the same problem or not... My 2005 Envoy XUV tailgate just stopped working this last week. A few days later, the swing gate stopped working too.

The window still goes up and down but even with the manual eject button (inside the cargo area) I can't seem to get the door/tailgate to open.

I checked (both) fuse boxes and found no open circuts... Am I wrong to suspect the door switches? Or is this likely a wire fatigue problem as in the previous posts? It really hasn't had that much use...

Thanks!

I think we've heard that the XUV is going to be a maintenance nightmare more and more as time goes on because of the switches.

[It is most likely the switches. You may be able to remove them externally by removing the screws above the licese plate and fishing them out. Otherwise you'll have to remove the inner panel and disconnect the wire connectors. Then remove the connector and inspect the switch. If you see a lime green material on the surface ithe copper circuit is corroded through and is most likely defective. A simple continuity test on the two pins will tell you. Open circuit when the pad is not depressed and a closed circuit when it is depressed is normal operation. ] After reading the posts in this thread I don't know mine is is the same problem or not...
