Five years of New England weather in this car, and I've never seen this happen before. I turned on the air conditioner and within a minute or two, I had condensation under the instrument panel. (Photo attached.) Today was muggy and humid, overcast, fairly hot.

I turned the climate controls to vent, fan all the way on and cold, lowered the windows, and pulled the trim piece away from the dash. It eventually all went away. Is condensation there something to be overly concerned about?

(FWIW, I have manual climate control.)

It'* possible with the humid climate that more moisture entered the dash area more than normal.
Or your vent is clogged up. The one on your firewall.

Hmmm is one of your ducts out of place?

Sorry for the delay. Ductwork is fine, but the foam on the back of that trim piece around the vents has seen better days. Any ideas?

Replacement sounds like a plan.

The AC foam that is self sticking etc can be found at Lowes and Home Depot relatively cheap.
