Default Water Leak under Glove Box

20181228_161712.jpg

All,

Please see attached. Any idea where this mystery water leak is coming from? I checked the A/C condensate rubber 90.

Thanks,

Jonathan

Did you verify the drain isnít plugged, I know you said you checked the 90, but did you check the passage?
If it doesnít smell like A freeze it could be a widow or cowling seal.

Do you have a sun roof? Don't know about GMC but I had a new 2018 Ford F350 and had the same issue. There are drain tubes coming from the sunroof and one came off. Caused a major leak inside on the passenger side because the water came down the inside of the pillar.

Water might be collecting under the windshield cowl trim and draining into the blower motor inlet. Had the same issue on a 08 mustang.

No sunroof.

Use an air compressor to blow out drain for condenser, I'd use 10lbs or less, I cleaned mine out with a piece of Monel from a ballyhoo rigg... Lol...
