A/c Not Blowing Cold....?

[OoltewahSpeedShop]

My 2500 HD A/C has started giving problems. First it started blowing warmer than normal, then about the same time it stopped blowing cold when I slow down or stop. Idling it blows no cold air at all. I checked the freon and it was a little low, so I added about half a can to get the pressures up to normal.

 

Nothing. Adding freon didn't help at all.

 

Any suggestions?

 

Thanks,

Kevin

Check you fan clutch. When you are idling, it should be fully engaged do draw extra air through the A/C condenser. If the A/C condenser isn't getting enough air movement, the A/C won't work.
