Im having major problems with my AC unit in my 2004 ram 1500(5.7). My AC don't blow cold at all. It just started bout a week ago. Before than the AC only blew cold when the truck was moving because the condenser motor went out. I was seating at a light bout a week ago and I heard a squealing noise from under the hood. It stop when I took off and ever since than the ac didn't blow cold any more. I believe it came from the compressor because the black ring by the compressor pulley is shredded a bit. Im on a tight budget. First thing I going to do is change to motor out of the condenser fan. What would be the next step? Should I change out the compressor? If so should I get a new one, take mines to get rebuilt, or is there some possible way I can fix the compressor myself?

 

Sounds like the compressor may have locked up. Does the center turn when you have the A/C switched on?
