1999 Chevrolet Blazer Q&A
1999 Chevrolet Blazer Question: S10 ZR2 Have wet carpet on drivers side carpet?
The drain you are looking for is probably the "evaporator" drain which is located on the engine compartment side of the firewall on the lower passenger side. When this drain is plugged the carpet on the passenger side is wet. You may have a door weather strip that is allowing water past. Water tends to run down behind the weather strip and come out at the bottom of the door. You may need to remove some of the interior peices around to door and have someone poor water on the door area so that you can see where it is comming in. - Russ
