2003 Suburban AC acting up

[jeffstally]

My AC cut out suddenly while driving down the freeway the other day and started blowing warm air. I checked the belt and was going to check the coolant pressure, but first I checked the 10 amp fuse under the hood. The motor was running when I pulled the fuse and it looked good. When I put it back in, the AC kicked in and was blowing ice cold air again.

Then tonight the AC quit again, I pulled the fuse and reinstalled and it worked again.

Any ideas?

Thanks
