Air Conditioning Leak on 04 Limited V8

[Barry Bombs]

I just experienced some pretty substantial air conditioning leaks in my 04 Limited while driving in the highway. After a decent amount of liquid, much coming from under the glove compartment, became evident I pulled over to a gas station. I looked around and could not decipher the problem, talked to an employee who thought it was fine, and got back on the highway puzzled.

The leaking continued once riding on the highway, and there is also a "swishing" noise of liquid in a container. I searched for similar problems or a TSB and didn't find any. Does this look like a serious issue, or just a minor leak/too much condensation?

I anticipate making a service appointment but I was wondering if this looks familiar to anyone here.

Thank you for your time..

Sounds like the evaporator drain is clogged. There should be a black rubber hose dropping from the firewall near the front crossmember. The swishing noise is trapped water released by the evaporator that is not draining properly. If you have your A/C running in park and don't notice a little pool of water under the car, sure sign of a clogged drain.

You can visibily see if mud, gravel, spider web, etc. is clogging the drain. I had a VW that literally formed ice in the footwells every time the A/C ran, which was alot. Turned out the A/C lines were installed backwards at the factory. I hope you have an easy fix.

I would have to agree with clogged drain.
