My 2003 F-350 has A/C issues. Used to be that when it idled for a while, or a lot of stop and go the A/C would shut off and blow hot. Usually on e you got going and got the air to flow over the radiator AC would kick back on, and I would notice the needledrop just a hair. So, I figured it was the fan clutch. Change that out, now the AC seems to go off whenever it wants. My wife made a 40+ mile run said it was sporadic when AC would work. I hopped in about an hour after she got home, drove it for 10 miles AC never came on. Any ideas?

 

Also forgot to mention, while my son was at baseball practice I went out to the truck and fired it up The AC compressor clutch was acting very erratic. Did look like it was holding good but it was turning on and off very quickly. Then after about a minute it clicked on and stayed on like it should. I ran around felt the air coming out of the vents, very cold. After baseball practice drove to the store blew cold the whole way. Then drove from the store to home, about five minutes, blew cold the whole way home.

 

Hosed out the condenser and radiator and ac seems to be good.
