I have on 01 CCLB F350 w the 7.3.For several years it had a very good ac,so much so Tonya kept a blanket in the back seat for long trips.In the last couple of years the a/c just hasn't worked as good.Last summer the comp clutch cover was soo wore out if just fell off and quit working.I put a new clutch and cover (shimmed correctly) and it was back to working but still not like it should.The summer before I replace the fan and while it worked it just wasn't as cold. My garage has been full and I haven't really had a chance to look at it close but Im about to tear in to it and want to know what I might be over looking or missing before I start buying parts. A/C condenser is beat up pretty bad down low.I am also having higher than normal trans temps and I feel the closed fins on the condenser are the problem since the trans cooler is directly behind the condenser.Could the extra heat from the fluid in the cooler be affecting the temp of the a/c?? Could heat be bleeding off the trans cooler back in to the condenser??? Fan speed seems to be correct w the switch position,when checking from the drivers seat.I am going to pull the fan from the box and check speed and also Im going to use a endoscope I have to check for a clogged evaporator.System does make water that puddles under the truck. Went to check the vent temps today and my vent thermometer was MIA.Got side tracked and didn't get back to it.Will try again tomorrow. Clutch does stay engaged,does not cycle on/off like its low on gas.I have an appointment later this week to put the gauges on it to confirm exact pressures. Blend door motor does seem to work but heater box under the dash seems loud(er) some times more than others.What is the correct way to test/check the blend door motor??? So what have I forgotten/overlooked/not mentioned??? Trying to have my ducks in a row before I tear in to it. @Tim C @RHSCTJ maybe????
