Do you have Onstar? Could be the antenna gasket leaking. Also, have you checked if your sunroof gasket leaks? Any water stains on the headliner anywhere? Your drain could also be blocked with dirt. Have you tried to blow it out?I have an 03 Yukon with sunroof and overhead rear a/c controls. Everytime it rain water drips from the overhead controls. Has anyone else had this issue? If so what did you do to fix the leak.

Tony,Do you have Onstar? Could be the antenna gasket leaking. Also, have you checked if your sunroof gasket leaks? Any water stains on the headliner anywhere? Your drain could also be blocked with dirt. Have you tried to blow it out?
Really not sure about the gasket replacement but I'd assume you'd need to tackle it by dropping the headliner from the front a little bit. Might be some bolts going through the roof from the Onstar antenna. The drain should be going through the A pillar( not sure if it's left or right side, but you'll know when you see it) Should be just a plain rubber hose that allows the water that pools where the sunroof is, to drain out. Just blow some of that canned compressed air through it. Compressor air might be too strong and cause the drain line to pop off somewhere--you don't want that. Luckily I have a plain Jane LS Hoe, so I've never had to deal with any of these issues, but I've been here long enough to know the common problems of what you're experiencing.Tony,
My Yukon does have onstar as a matter of fact. Never even though that could be the problem. I have not stated to investigate any of those possible problems. Where is the drain located? Is it hard to replace the antenna gasket? I will start troubleshooting it all these suggestions once it stops raining.
