2000 9-5 SE Wagon. When running the A/C, water accumulates in backseat floor to where it is standing water. A/C guy replaced drain tube, blew out drain hole with compressed air. This worked for a few months, but started collecting water again. Recently had seals replaced in evaporation pan, evaporation plan cleaned out. Did not even slow water down. Anyone ever heard of this problem or have knowledge of SAAB A/C. Local SAAB repair guy and dealer have never seen this before. By the way, looking to sell this vehicle as soon as this problem is resolved. Anyone interested?? 101K miles, good condition, loaded, leather, sunroof.
