Compressor not Receiving Voltage (Need quick help if possible, currently at regional)

[Arthur3103]

You need to prove that parts of the system are good. Start at either the PDB or start at the compressor. Test one component at a time and be methodical.

Check the wiring from the PDB to the PCM. Take out the wires and reinsert them in the PDB and PCM.

Take out the compressor wires and reinsert them.

Remove the PDB fuse and push it back in again. Perhaps change the PDB fuse to a spare.

Will the compressor run when given 12v from another source - do not connect to a tank if trying this. You want the compressed air exhausting to the atmosphere for safety.

If the compressor is good, test the pressure switch.

Good luck.
