Did you clear the low refrigerant code?

 

Yes! All codes clear except for the air suspension code

 

Maybe the low pressure switch is bad.

That said, you are going about this bass ackwards. You should have replaced the orifice tube, accumulator, compressor and condenser (ladder style condensers cannot be flushed) BEFORE recharging it. If the orifice tube was clogged, there was also debris in the rest of the system which may have made it's way back to your new compressor. Don't be surprised if it doesn't last as long as you'd expect it to.

 

Ok but before I throw parts at it, how do I find out if the switch is actually bad? With the switch unplugged I have 1 hot connection and a ground. But when plugged in both sides become hot, not the case for the 2 high pressure sensors. Plugged or unplugged it has one hot wire one ground wire, and again I have no acp codes

You could try jumping the switch.

 

Where can I get the complete diagram of the a/c system! 94 cadillac deville 4.9l

 

Ok, I jumped the low pressure switch and as previously stated both wires are live is this normal?

 

I also need the wiring part as well so I know how the currents should be running!

 

I'm not sure where you'd find a wiring schematic other than a FSM or a subscription to alldatadiy.

I'm not sure how that switch works. Does it run OK with no codes when the switch is jumped? If so, the switch needs to be replaced.
