Water in the cabin air filter slot

Derick · Jul 10, 2020

So I'm doing the cabin air filter retro install, and i drilled through the slot where the cover goes and I get water dripping out of it. Not a significant amount but enough to warrant a WTF moment.... where is it coming from and why?

been thru the car wash recently? it could be that or possibly condensation

Likely, if it is water and not coolant, a blocked a/c condensation drain hose at the firewall on the engine side. That is the sweat of the a/c evaporator that builds up during a/c usage and defroster usage. If is coolant, then suspect a heater core problem. If you dab a bit on your finger tip and taste, is it a water taste or the sweet/sour taste of coolant?

Also, like I just read what Wes said, possibly the car wash or heavy rain and leaks from the cowl area.

You could probably just smell it to determine if its antifreeze

It's not that bad if you have a double shot of Jim Beam to wash it down with. I grew up around lead paint and lived to tell the story. I also inhaled brake dust before the guidelines and again, I am still kickin' ass and takin' names.
