2002GMC YukDenali-Loc of AC drain plug/drain tube

[chris ferguson]

I have noticed damp carpet in front passenger carpet and second row passenger side. Have read the drain plug under hood could be clogged and the drain tube under car. Pulled cover off inside to ensure cabin filters were ok and no water in here. System blows cold air. This just started in the last 5-10 days.

I crawled under car and cannot see any drain tube. Under hood not sure which is the drain plug to clean. Do not want to pester the AC system.

Appreciate any photos/guidance.

On the firewall passenger side of the vehicle you should see a short tube protruding through and possibly with a 90 degree bend toward the ground. Some systems just go straight down from the evaporator box to the ground again on the passenger side of the vehicle but underneath. If your vehicle has rear A/C there will possibly be another drain tube for that unit too. Designs vary. Hope this helps a little.

Maybe this will give you some idea….

Try on the passenger side under the heater hoses.
look for a rubber elbow.
