A/C not working
Hello everyone I'm back, after searching all the post I can, I've still not found the answer I want or need. I have a 04 f250 6.0. Just replaced the a/c compressor A/C was working great until the clutch bearing decided to fail.
Replaced the compressor placed two cans 134A jumped the low pressure switch not working. To make sure the compressor is good I jumped a hot wire to compressor and it worked, the fuse is good I don't know where to go from here.. Can anyone Help Thanks

Remember the A/C clutch is on a seperate fuse. Did you pull down a vacum on it before adding the 2 cans? Did you jumper the low pressure switch? IIRC it takes 3 cans before the clutch will stay in on it's own and it will cycle properly.

A/C working
A/C working now but the coolant fan isn't working with the A/C on. The fan works or seems to work but it should come on when I turn the A/C on. Is there a relay or switch that pulls the fan on?

The fan is PCM controlled and there is more than one parameter that's considered. Try turning the A/C on max cool and see if the fan operation becomes a bit more robust. As long as the truck isn't overheating it's fine.

A/C Not Working
Can't believe no one knows the answer to my question!!
Where is the fuse or relay for the coolant fan located? on an 04 F250 6.0
and the fuse box isn't under the hood it's under the steering column.

You have 2 fuse boxes on a 6.0. Yes the voltages to the cluch fan are PCM controled and variable because the fan is variable. It is not just on and off.
As previeously mentioned several sensors are involved with A/C and clutch fan operation.

The fans on these trucks don't come on fully like an electric fan on a car.
If you have high pressures spiking in the A/C system then you may have a clogged orifice. When I change out compressors the orifice tube and dryer get changed and the system is flushed.
Also check for a clogged condesor. Dirt and bugs will restrict air flow making it inefficient.
