compressor is not spinning does this mean I can not charge ?
Cadillac Mechanic: Eric, Automotive Repair Shop Manager replied 2 months ago

Hi,

You will need to jumper the low pressure switch as it is preventing the compressor from kicking in due to low/no refrigerant. If you look at the ac line at the firewall, you will see the low pressure switch - see attached diagram

Remove the connector to the switch. on the harness side connector, use either a small wire with each end striped or even a paperclip to insert between the 2 pins. With ac switch on, it should cause the compressor to kick on and accept the refrigerant.

If not, then there is another issue and will need diagnostics done.
