A few months ago the AC in my Civic stopped working properly. It gets warm when the car is driving but will return to cold when the car is idle or stopped. I replaced the compressor clutch, pressure switch, and the evaporator core temperature sensor. I also had flushed out the lines and recharged them and gave the compressor new oil. I cannot figure out what seems to be the problem and I do not want to take it to mechanics because it's too expensive but replacing everything else to do with the AC would also be expensive if I don't know what exactly is wrong. There are no leaks in the lines and none of them are logged either. I'm also not sure if it's just an electrical thing or a mechanical thing. Please help if you have ever had this problem or you have seen something like it. I think a hint into what is wrong has to do with the fact that the AC will only blow cool air when the car is idle. The heat does work though.

This one is a bit strange. I would say take a good look at the condenser and the fans. Perhaps one of the fans is wired backwards.

Blend door issue? It should be getting colder the faster you go.
