I have an 06 Dodge Dakota with a peculiar AC issue that I need some help narrowing down.
-AC always works on start, gets cold, and blows at set speeds
-After about 15 minutes, if it is hot and humid outside, condensation builds on the ducts.
-At highway speeds after about 30 minutes, the duct by the drain tube freezes (see picture). Ductowrk behind dash sweats.
-Once the freezing begins, the air output gradually slows down, but stays cold. Air blows at lowest setting even when set on high, however when the speed is set to high you can hear it sounding like it wants to blow harder, but no additional air comes out. I am assuming the freezing is blocking the path of air.
-NOT A DRAIN TUBE ISSUE. The drain tube has been cleaned multiple times.
-When the car is off, the drain tub dumps an incredible amount of water compared to what I have seen on other cars.
-All this occurs when using AC on fresh air mode. If you put blower on recirc, all of this still happens. but not as quickly.
