The low pressure switch is located on the accumulator, and you only need to remove the connector to the low pressure switch and jumper the wire connector to by-pass the low pressure switch, however I would not recommend doing so because it is there to keep the AC compressor from being damaged due to running it low on R-134a.

If you are trying to charge the AC system you do not need to by-pass the low pressure switch, just start the vehicle and turn the AC on to maximum, then charge the AC system and when there is enough pressure in the system the compressor will come on, and then just continue to fully charge the AC system.

Why is my car giving an incorrect error?


Check or replace the pressure switch on the ac dryer. It is shutting off and not allowing the compressor to run. This based on the system having the right amount of R134A.

Where is the low presure switch at for the air conditioner on a 1995 lumina car?


I can't be EXACT, BUT it should be on the receiver/drier. Which may be close to the firewall and buried by a cover.

Or follow the low pressure side lines.
