This was one for the tech books.. thanks for your help

 

I had a similar problem for a while. I just discovered that the AC system has a drain hose and mine was clogged. The hose comes out of the bottom of the system under the dash on passenger side and about a 3/4 inch rubber drain hose goes thru firewall. I took off the hose and it was clogged and so was right inside the A/C system outlet hole. Cleaned out both and it is draining like crazy.
