So I replaced the compressor and got my AC working about 1.5 months ago. I also put on a new drain plug. Up until yesterday condensation was draining great. There was always a nice big puddle of water forming under the car. This morning there was just a tiny little 2" puddle, and the passenger floorboard is wet.
I checked the drain plug and it is attached, and perfectly clear of any debris. I had this problem the last time the AC worked a year ago, but I didn't have the drain plug at that time. Since everything was dry and draining this time I thought that the problem was solved. Now it's back, and I'm afraid I know what the answer is, but can anyone think of anything I can check to fix the problem without having to pull the dash and examine the evaporator case?
I don't understand why it would be draining fine, and then just stop. Maybe some debris in the evap case blocking the drain?
