2006 Chevrolet 2500 - A/C Problems

My air conditioner blows cool air sporadically - the cool air feels slightly moist. Replaced the cycling switch but still having issues

Have someone check if the condensate drain tube for the AC is plugged.


My 2005 Sierra did that. It would feel like the compressor was cycling on and off while riding down the freeway. In my case, it was slightly low on freon.
