[Solution] Fix Sunroof Leak 07-13 GMC Sierra Chevrolet Silverado 08 09 10 11 12

TSB from GM: https://www.tsbsearch.com/GMC/09-08-5... FIRST LEAK LOCATION (Condition 3 in TSB): In this video I discuss my troubleshooting efforts and repair to fix a leaking sunroof. The driver and passenger rear drain tube assemblies (plastic) that attach to the drain channels (metal) have silicone attaching them to prevent leakage. The seal had deteriorated so I cleaned them and reapplied silicone. This fixed the first leak from the sunroof drain that I was having. SECOND LEAK LOCATION FOUND AFTER THIS VIDEO WAS SHOT (Condition 3 in TSB): After the repairs above I still was having a leak from the rear c-pillar on the driver side(where the drain hose is routed into). (To note: this is a separate leak because the location I fixed in the video was also leaking) To access the rear c-pillar I had to remove the rear seat. (The rear seat is removed for 60/40 seats by using a 19mm socket to remove the 6 bolts holding it down.) Upon inspection, I found that the rear c-pillar has foam in it to create a barrier from the outside of the cab to the inside; there is a drain hole around the foam. This drain hole on the drive side was clogged. I tested the other side (passenger side) by dumping water down its C-pillar and it drained out the back of the cab (if you look under the cab at the back corner of the cab you can see this location), when I did this with the rear driver side, it leaked into the cab and no water came out the back of the cab. Using a thick medal rod (*evil laugh*) I punctured a hole through the foam to create another hole (as I couldn't really find the original drain hole), I also ran a tube through this new hole so it doesn't seal up again. Tested it and it worked perfectly. NO more leakage in my truck!!! My initial troubleshooting efforts: 1) Checked front drains, verified clear by pouring water in front channel 2) checked rear drains by removing rear column trim to access the rear drain tube. Poured water down side channel and found leakage near sunroof. Although some water did come out the drain (verifying clear). 3) dropped the headliner. Poured water in side channel and found water leaking from rear plastic union that holds the rear drain. To Fix rear plastic drain assembly: 1) remove plastic union. Detach hose. 2) clean off old silicone with acetone. 3)put new silicone in lower plastic body. Reattach hose with cable tie. 4) reinstall plastic union. Let sit for 8 hrs up to 24 hours. I used a 30 min 100% silicone. 5) Tested 8 hrs later and it worked perfectly.
