Where is the low pressure ac port on a 2000 saturn L200

SOURCE: ac short on 2001 saturn l200

Does the A/C compressor run or does it blow the A/C fuse in the under hood fuse box?? If it's blowing the fuse you might have a bad A/C diode located in the underhood fuse block.It looks like a black fuse with a diagram on top of it.Pull it out & replace it & see if the problem is gone.These L series are notorius for having compressor problems,locking up,clutch coils going open.hope this helps

SOURCE: saturn ac wont blow cold air

check cooling fan operation while ac on.If fan is working proper,will probably have stuck exspantion valve.

SOURCE: 2000 Saturn SL1, need to locate low pressure

The gauge only fits one port so you can't hook it up incorrectly basically. It wasn't always that way. The old days with r-12 you could make a mistake but car manufacturers finally did something about it. I know the first time it's a little scary, but after you do it,no problem. Have fun!

SOURCE: AC booster recharge hook-up

You can only attach the the recharge hose from the kit to the low side ( A/C service port) and the cap should be blue with a leter L on it. Good luck and follow the instruction and don't over charge the system. With the AC on the coldest setting, use a thermometer in a middle vent. Normal vent temperature readings will vary depending on the (ambient) outside temp. The vent temperature should range from around 42-55 degrees in my experience. If normal gauge readings are obtained and the vent air is cold - STOP don’t overcharge the system. The only proper way to remove refrigerant is with a AC recovery machine so if this is being done at home I can’t emphasize enough not to over charge the system. And actually the best way to insure the proper charge is in a system, is to use an AC machine to recover the R134a and then evacuate and recharge the system with the correct amount. Most cars have the specified amount on a decal under the hood.  Good luck and hope this helps.

It will be located on the large line that runs between the a/c compressor and the fire wall. I believe it will have a black cap on it. Check the accumulator canister, it may be located on it.
Make sure you use the port on the large line.
Let me know.
