History:
Checked pressure with manifold gauges (80 psi both low and high).
All control lights are working.
Ran DPT self-test (no errors).
Clutch doesn't engage with a/c on (can spin manually).
Turned on A/C and depressed clutch with pry bar. I can hear the friction, but it never engages.
Checked relay (by substitution) and it is fine.
When A/C is on, condenser fan is running.

Addendum: Jumped the compressor clutch to the battery. Clutch now engages. Still doesn't blow cold.

Thanks for visiting 2CarPros.

Verify that you have 12 volts at cavity 30 for the clutch relay, fuse 58 feeds that. If you do have voltage on 30 check resistance from cavity 87 to the clutch. There may be a break in the wire.

I'll post the diagram below, this section is identical for manual and auto AC
