If the HVAC (heater) housing is not properly sealed at the bulkhead (firewall), water can leak into the passenger compartment. Foam sealant should be used to seal any gaps and the evaporator drain tube can be modified to prevent further water entry.

Water builds up in the floorboard of the front passaenger seat of the van. Carpet is showing signs of mold. I need to find a way to fix it. One article said to use foam, but where are the directions for this? I want to sell/replace the van, and no one will want a van with a leaky a/c.
Water leaks in around the seal at the firewall. I have not fixed it yet and would like to know how to seal it. The tube or water exit in the engine compartment is open. Input on how to fix it is requested. Thanks.
water leak onto front passenger side compartment/floor-board when a/c is being used. I saw the comment advising to use a foam sealant. Do I have to take the dash apart to get to it? Is there possibly a plastic part that may have broken? THANKS for your advice!!
