air conditioning condensation behind vents gets carpet wet

[jerrycastillo]

Hello,

The metal housing behind the AC vents and the fan housing get very cold from the AC and get wet as the highly humid air is condensed at their surfaces. This condensation runs down and ends up wetting the carpet on the passenger side.
Has anyone encountered this same problem?
I thought I might cover the metal surfaces with self adhesive foam to avoid condensation. Any ideas will be welcome!!

Thank you!

There are usually insulation blankets n the inside of the cabinet. Yours may be deteriorated or missing. Rigid closed cell panels like those used for windshield sunshades work well as a replacement. I think you can remove the bottom cover without removing the unit. Others may know. Attach with spray adhesive or contact cement. Any local heating and air shop has this stuff.

Thanks Tyler for your suggestions!

Anyone has ever disassembled a Frigiking underdash AC unit? I would like to open it and clean it inside. I would appreciate any procedures, photos, etc.
