Side Foot Well (?) area Wet after turning on AC

JRob23 · 08-18-2016, 07:08 PM

So long story short, I'm driving with the AC on and happen to brush the right side of my right calf against the fabric and notice it's wet. I put my hand up close to where the trim meets the fabric and can feel cold air slightly coming out of that area as if something wasn't properly connected and leaking out. I compared to the other side, it wasn't wet nor was any cold air 'leaking' out of where the trim meets the fabric.

I didn't want to initially provide too much of a background as to not lead to any preconceived notions. Thoughts?

My guess is Clogged ac drain pipe causing condensation water to come out where it shouldn't

Thread revival!
I just had this happen the other day. Any update on what you did to solve it? I noticed it happened after taking a clockwise on-ramp at high speed. Leading me to think that the water drained and was forced left instead of down. Normal?

Have the vehicle running with the a/c on, and look under the car, if you don't see water dripping, you have a clogged/partially clogged drain pipe for the evap box.

Gonna have to get under there and un-clog it.
