Is hood fuse 35 or dash fuse 13 blown?

If the fuses are fine, try jumping the pressure switch or the thermostat.

Relay might be stuck, i'd run a jumper to see if it turns on

Use a paper clip to jump from i belive what is Socket 38 or whichever has Power Constant, to the one diagonally from it

Kind of hard to diag without a manifold gauage set. too low of pressure could cause the system to not operate. does the system have R134 refridgerant?

Did you replace the fuses I mentioned with known good ones?

Unplug the 2P connectors and install a jumper wire that shorts the terminals.

The 2P connectors for the thermostat and pressure switch have 2 wire terminals. Get a piece of wire a few inches long and remove the wire insulation at each end. Then insert the ends of this "jumper wire" into each terminal of the 2P connector.

No.

Do you know how to pull CEL codes by jumping the 2P service connector? It's the same concept. Click here.
