Question about 2002 Saturn L-Series
My air conditioner stopped working about 10 months ago at the end of the summer. I didnt think about recharging it because winter was about to hit. Since summer is approching, I thought Id go ahead and recharge the conditioner myself with the proper coolant my manual said. I bought a can with the gauge so I could better know what is going on since it is my first time. (I am not a car gal, I am a premed student lol) So I had my neighbor (car guy) put the entire can in while I had the vehicle on running full blast on cold with the A/C button on. As we filled it, still no cold air. Then he noticed that my compressor was not clicking in. We checked all the wires and have yet to check the fuses (which I am uncertain which fuse to look for). The car has 100k on it just as of last month (April) and the coolant we bought is supposed to fix leak but how is it supposed to fix them if the compressor isnt turning on. I did reset the battery thinking it was a computer error but still no fix. Please help, thanks!

The compressor clutch has a relay that energizes the A/C comperssor clutch an The PCM / ECM - engine computer energizes the relay . what you have posted here ( I did reset the battery thinking it was a computer error but still no fix) . Will do nothing ,you people think resetting the computer can fix anything ????? Take it to a qualified repair shop that knows how the system works . There are high an low pressure cut off switches ,maybe the clutch coil is bad . Could have DTC'S - diagnostic trouble codes . Hooking up A/C gauges is also a must , you do not want to add refrigerant if it doesn't need it .

Sounds like a body control module. It is located on top of the glove box. Unfortunately, the miles are stored in this module, so you have to go to a dealer to have it programmed.

There are two A/C refrigerant lines. The small line is your high pressure line and the larger line is your low pressure line.
Start at the fire wall and follow the "large " low pressure line to the compressor. The low pressure charge port will be some where on that line.
DO NOT try to recharge on the high pressure side ( small line )
Good luck, let me know.

yes their is a switch that senses the amount of gas pressure and shuts down system if their is not enough pressure,but playing with a high pressure system like this can seriously maim,so iam advising you to take it to a repair shop with a proper machine to discharge the system and then check for the faults ,but most likely cause is lack of reserve gas in the system and it just wants a re gas
