Do your windshield wipers also stop working? If so, the most likely cause is your Body Control Module (BCM). The 1999-2000 GMC Denali was known for having issues with the retained accessory power relay solder connection inside the BCM. If you're up to the task of removing the BCM (located inside the center console- kind of a pain to get at) and know how to solder, you can fix it. Otherwise the BCM will have to be replaced.

You have to reset the windows and sunroof after you change the battery. For windows open the driver half way and close the window up and hold the up switch for few seconds. If that don't work open the rear window from rear switch and that should work.
For moon roof open the moon roof and keep the hold the open button pressed for 10 seconds. Then close the moon roof and hold the close button pressed for 10 seconds

The power windows only work from driver door. child safety switch is off. the power locks work from passenger door tho. i checked fuses but dont know what is wrong?

Try pressing the child safety window lockout button 20-30 times and see if it starts working. This has worked a few times for me.

A few things

definately sounds like a fuse problem, check all the fuses in your fuse box and be sure to replace them with the right amp fuses

Power windows not working

Hey...I went through the same problem. It seems that if you have the stock mac stereo system and the fuses are not blown up, is more likely that your three amps do not work either. You have to rewire the car's stereo system from the car's stereo directly onto the speakers or an amp if you choose to include more sound. As for the power windows, as frustrating as it may seem, change the double throw double pole in each door. The connectors corrode from the inside. Try scraping off the copper metal and it will work for a few days and it will not work again... So just reorder a new from Ford. They run up to 40$ ok? Ben
