1994 E150, Is there a fuse for the A/C compressor? If so where? Book does not show one.

 

Hi Rusty,

Fuse #9 in the interior fuse panel (15 amp) when key is on provides power to to the function selector sw , and based on where that is positioned (A/C) supplies power to the A/C cycling sw that is located on the Rec/Dryer. When the sw is closed it passes power to the compressor clutch No refrigerant charge in the system will not allow the sw to close as also will too hi pressure in the system
Power should be present at one of the sw terminal wires when A/C is selected. That power then is sent on down to the compressor clutch..

As you know if power is present at the clutch it must also have a good ground to work if clutch coil is good..
System must have some refrigerant in it to work.

If there is anything else you need , will try to assist.

 

Although anything is possible and the clutch fuse could be blown but there are more likely causes for an inactive compressor clutch. Fuses blow for a reason and do not wear out. A low charge of refridgerant due to a leak is a much more likely cause for the compressor not to activate.
