Sunroofs are worthless IMHO. I have only one and it is in my 2006 Pontiac G6 GTP because I couldn't find a GTP without the sunroof. I have had it taped over for 10 years to keep it from leaking. Absolutely worthless.

 

Thank you for all of the valuable information. I will touch base when some of the troubleshooting has been done.

PS: These trucks are kind of a headache. This is just one of many issues we have with this thing. Fuel injection that needs replaced, transfer case that doesnt come out of 2WD, LF seat that wont move, batteries that keep being drained after just a few days, LF door that wont shut properly because the hinge "bearings" keep going out. But the wife loves the POS so I keep working on it.

 

You are welcome! Good luck with your repairs.
