    I have checked the charge and it is full, the fuse is good, swapped the relay, Blower works fine, but compressor never comes on. What should I check next?

    check your cycling switch its over on the dryer unplug it and take a paper clip and stick it in the plug turn on the truck and see if it comes on if so then you can pick up a new cycling switch at any parts house for a few bucks if that does not work then you might wanna check the high temp switch in the back of the compressor to see it its melted or damaged and its about 30 bucks at any parts house also

    thanks, the cycling switch seems to be the problem. It came on by shorting out the contacts. Thanks again.
