Saturn 2002 L200 Air conditioner problem

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.

SOURCE: AC has stopped blowing cold air. Compressor is working. Where is the recharge valve located?

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.
Regards,

SOURCE: 2002 Saturn L200 A/C compressor is not engaging.

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

Air Conditioner Problems


you may have had an electrical problem all along and now you've added Freon on top of a full charge which isn't good. put the gauges on both the high and low side. and see if you are charged or low or overcharged. the compressor can go out on high pressure or go out on low pressure. I am not sure which you have. thwere are relays that come into play when the charge is high enough to satisfy the low pressure switch. the relay is in the power distribution box under the hood. there is also a fuse under dash for the ac

Difficulty finding air conditioner parts for my 1999 saturn sl. air has never worked well since we bought in 2004.


Saturn parts are easy to find at car parts stores, many GM dealers, eBay, and at getsaturnparts.net. It is 12, was designed to run well for 10 years. Many many parts on that car are simply GM parts, and most of them are just worn out.

You can do a little googling and find your local GM dealer which was saddled with the Saturn warranty issues when Saturn was shut down a few years ago. They can help you find parts and expert tech help but their labor cost will exceed the value of your car on all serious repair issues.

Take the car to a repair shop which does heating and A/C work on cars. Have them tell you which A/C parts are beyond the end of their service life. Then buy new or rebuilt parts, have them install the parts and charge the system. There is a condensor, a compressor, an evaporator, a dryer, and some hoses, all of which can be had new over the counter.

I had a bunch of saturns and i think the 99SOHC was the best of them, great mileage. I drove mine for years with no A/C then gave it to my girlfriend who immediately pitched a ***** about the A/C. I had to buy and return 4 junkyard compressors before I found one that would work. The labor for install and charge was about 150, the junkyard compressor 55 so i had some trips and about 200 bucks in it. To buy a rebuilt compressor about 300 bucks alone so i saved money and it still works 2 summers later. The good mileage is gone when you run the A/C so windows down and cloth seats were all the A/C I ever needed.

We have a 2002 saturn L200. The air conditioner is not working. It blows air, but only hot air. On some cars you re-charge the system. I remember doing it on my older van. Is it posible to do this on...


You can swing by your local auto parts store and get a can of R134 refrigerant. Many times you can buy a can that has a low side fitting attached to it and it may also have a small gauge. Under the hood there will be two ports for the a/c systmem. You'll need to find the fitting on the larger diameter line. This will be the smaller of the two fittings and called the low side fitting. The fitting on the can of r134 will only fit this fitting. Start the vehicle and turn on the a/c. Then install the fitting on the can to the fitting on the line. Follow the instructions on the can to fill the system. It will take 10-20 minutes for the can to empty. You should hear the compressor turn on during this time. If the can does not empty and the compressor does not turn on than there is another problem. If the can does empty and the a/c compressor turns on and cold air starts to blow out the vents than you good to go. If the air out the vents is cooler but not cold you may need to add another can. If that lasts the summer than no problems. If the a/c starts to blow warm again in less than a couple of months you have a leak in the system. It wouldn't be a bad idea to have it checked to see where it is leaking. Most places will do this for under a hundred dollars and if you shop around you may find a place having a special as many do in the summer time. Good luck. Let us know how it turned out.
