Just had my AC system repaired and converted to 134A. It's not cooling well in the heat of the day. This afternoon I had to make a quick left turn, and a bunch of water dumped out of the bottom (air intake) on the passenger side floor board. I found an empty parking lot and made a left turn circle for several minutes, and dumped a bunch of water into the pass side floorboard. I'm assuming my evaporator drain tube is plugged up. Can someone direct me to where this is located at? Would this cause the system not to cool properly when the heat and humidity in s high?
