I'm having issues with the coldness of the A/C. It is blowing mostly warm to hot air at idle. It will become cold if you're driving at about 1,500-2,000 RPM but then will get warm again over 2,500 RPM.
The interior fan is blowing just fine. I checked the refrigerant level and it was at 55 PSI. I'm lost as to what is causing this. At idle and when not quite up to temp, the coolant line that runs across the top of the radiator/fan shroud assembly will rattle and vibrate. The sound has no effect on the temperature of the air though. I have a video of it that I'm trying to figure out how to post.
Anyone have any ideas on where to start? My first guess is compressor fan clutch but is only a guess. Thinking of surrendering early on this one and just taking it to the shop first thing in the morning to have them diagnose it.
