    Have you actually tested for power, or are you assuming that there is no power because it's not turning on?

    . Test all underhood and underdash fuses with a test light or multimeter:

    There is an A/C Clutch Relay fuse, in the underhood fuse/relay box.

    . Check the A/C Clutch Relay, in the underhood fuse/relay box.

    Test for power through the fuses, since corrosion may have formed on the contacts. Remove and clean with steel wool or abrasive cloth, if necessary (one at a time). Similarly, you may want to remove the A/C Clutch Relay and clean the contacts. Lightly coat all contacts with dielectric grease. Underhood fuse/relay boxes on trucks often get really dirty inside, especially when they are used on ranches.
