2022 GMC SIERRA DENALI DRIVER FLOORBOARD WATER/CONDENSATION

[Nathan916]

I have a 22 Sierra Denali. Somehow water is getting under my carpet and insulation on my driver side only. I thought it could be a door seal or the antenna but I took it through the car was with the carpet lifted up and flash lights and there was absolutely no water getting in nor when it rains. I also don’t think it’s coming from the air conditioner because the only spot that continues to show condensation is the driver side the passenger side is completely dry. Any ideas on where this condensation/ water coming from? Any advice recommendations would be appreciated

Welcome to the forum. Do you have a sunroof?

Having this exact problem. Did you get it figured out. The dealer said it was a clogged sunroof drain and fixed that but it’s still happening.
