Where is the AC Receiver/ Drier housing the AC low pressure switch on an '04 grand am? Either I am completely overlooking or it was horribly placed. I am needing to jump the switch in order to engage to AC clutch to allow a recharge but cannot locate the switch itself. I would appreciate any help! Thanks.

According to my locator it doesnt have a low side cycling switch, just a refrigerant pressure sensor.If you hook up the refrigerant to it, when enough static pressure is in the system it will turn on.It may take a few minutes to build that much up though. Here is video to help you recharge the system with the sensor location below.
