My sunroof window won't close when I press the button on my 05 Envoy. Any idea on repair cost to get it to close?

This could be a number of things and you'll have to take it in of course to get it properly diagnosed: 1) The window might have come out of its track. This is a fairly simple, quick and inexpensive repair. 2) Something in the mechanism that raises and lowers the window may have broken. It could be one piece of the mechanism...it could be several pieces of the mechanism. This is a slightly more complicated and slightly more expensive repair than #1. 3) Power windows obviously require electricity in order for the switches, relays, actuators, and motors that move the windows up and down to function. You might have a blown fuse, which is an easy, quick, and inexpensive repair. Or...you may have a serious problem with the vehicle's electrical system which could be an expensive repair. Even if it is a serious problem requiring an expensive repair, if you're unable or unwilling to pay for that repair the shop should still be able to move the window manually into the closed position to prevent wind, snow and or rain from getting in, however you may not be able to roll that window down again until you make the repair.
