Engageing A/C Compressor Clutch

Locate the low pressure cutoff switch on the line going into the firewall. It should have two wires in the connector. Jumper those with a paper clip. You can also pop the cover off the clutch relay, reinstall the relay, and squeeze the contact.

If the refrigerant still goes in slowly when the compressor is running, place the can upright in a pot of hot water.
