Check the following items.........
1. Freon levels.
2. Electrical harnesses for the a/c system.
3. Clutch air gap.
4. Pressure switches.....
trying to replace the ac clutch on my f350 6.0 and the bolt up front seems to be a special one any sugestions
low freon
Turn on ac and watch clutch on front of ac compressor. If clutch doesn't engage then AC relay is bad. Or you can follow the schematic on the side of the relay and use a volt meter to test it.
To test the AC compressor on a 1993 Ford Ranger with a 4.0 V6 engine, start by checking the refrigerant levels to ensure they are adequate. Next, with the engine running and the AC set to maximum, observe the compressor clutch; it should engage when the AC is activated. If the clutch does not engage, use a multimeter to check for voltage at the clutch connector. If there is voltage and the clutch still does not engage, the compressor may be faulty and require replacement.
You could have air in the lines
Most Likely Low With Freon.
The a/c clutch will not engage and the compressor will not come on.............
check fuse or ac relay in under hood fuse box.. if out of coolant ac clutch will not engage,this is a safety feature!!
It is a hydrolic clutch does not need adjusting
The 2003 Ford F3 50 air conditioning clutch relay switch can be found on the firewall in the engine compartment. The air conditioning clutch relay switch will be on the passenger side of the firewall.
The clutch receives it's signal to engage from a pressure switch in the system. If there is insufficient refrigerant in the system the pressure switch will not close resulting in no power at the compressor clutch to make it engage.
You have vacuum line leaks somewhere.
