Finally after putting up with wet floors for 16,000 miles on the passenger side, I went to a totally different dealer that found the problem. The compartment that houses the A/C and heater was cracked. The condensation from the A/C leaked on the floor and eventually even ran into the back floor. 2 1/2 days later and a lot of cursing by the installer, I have my Av back and NO LEAK!!!!!!!! They told me that they have had quite a few do this.
