Sunroof won’t open makes noise
I got a new to me, 2006 Hummer H3 with a sunroof and when I press the sunroof button down or up it doesn’t move it makes a struggling noise. Not sure if it’s the button or motor. I tried looking on this forum for similar problems as mine but can’t find any, anyone with tips let me know thank you

Yeah maybe, I click it and it makes a noise as it’s trying to move but the windo stays still. When I click it backwards the sunroof will move a little the first try and actually go a little backwards so the sunroof pops up from the back then when I close it it closes all the way and will struggle to make any more movement.

If it never/rarely gets used, the rubber seal may have adhered to the glass frame. Try and work something around the seal that won't cut (popsicle stick?) to free it up. If that works, and allows it to open, spread a film of silicone grease on the seal.

If it's "making a noise", "moving a little", and "popping up in the rear", then that tells me the switch is sending current to the motor. My guess is it's not the switch.

Sounds like either the track guide is broken or the cable has skipped/broken teeth on your sunroof motor.
Either way it's headliner removal might as well clean and reinforce all of the sunroof drains while you have the headliner off. Plenty of YouTube vids on the tubes.

In my early days I was employed by an OEM sunroof manufacturer WEBASTO.
You should be able to find YouTube videos of motor replacement and/or diagnostics. AS long as the video is of a front motor it will be pretty much the same as yours.

so I was able to pull out and inspect the motor and everything looked good, the switch looks good as well I cleaned the motor and it’s actually closing the sunroof strong now but it doesn’t open, does anyone know where to locate the tracks or how to repair them? That’s the next step
