My 03 ac does not blow cold air. The pump kicks on and never shuts off, but the vents blow hot air. The ac lines going into the cab are ice cold (ice on the line). Coincidentally, the passenger floor board is soaking wet. It does not smell like antifreeze. However, it has been raining for several days pretty much non stop. I am curious if these problems are related or if they are two different issues? Also, after reading some posts it seams that the vent door has been notorious for breaking. Would this cause the ac vents to blow hot air and could it somehow be related to the wet floor board. It appears that there is a drain located on the fire wall. I inspected that and used a coat hanger to see if it was clogged and nothing came out. If the vent door is bad, how big of a repair project is it? Do I need to take out the dash to do it, or pay the dealer? Any help would be greatly appreciated. Thanks.
