It all started when I replaced the Battery,
Seems like the next day I couldn't get any cold air. I checked the fuses and relay they are fine. What the heck.

You need to work back looking for power. Check the relay.

I checked the relay, actually I swap out the relay with the horn relay, and the horn still worked, so just assumed the A/C relay was good. I guess I'll start from the plug and work backward. I have had a problem with pack rats. Eating through vac. Hoses.
Thanks for the info, and your time.
I thought maybe there was something I was missing.
Thanks again.

Hey guy's spent most the morning chasing down a solution.
Wirng is all good, I believe that I am low on R-134a.
After chasing wires I finally started the truck and jumped across the contacts of the cycling switch. The clutch engaged. Still blows warm air after 5 min.
I'm not clear on which tap is the low side, Is it the one on the accumulator?
Thanks again for your help.
