Has anybody experienced this? I've looked thru discussion groups but I have not found anybody with an Expy having this problem. From what I read it seems that it could be a tube clogged that then fills up the evaporator and when it overflows gets my carpet wet. Any input would be appreciated. Thanks.

 

A clogged drain is what you have. Some are very hard to find. To locate it find the two lines for the a/c at the point where they go through the firewall. The drain tube will be very close to directly below the lines and close to bottom of the firewall. If the evaparator case is in the engine compartment the drain will be on the bottom edge of the case close to the firewall. If the lines are close to the wheelwell the drain could be out of sight in that area.
