Question about 2001 Saturn L-Series
This is a 4 cylinder right? Open the hood and look down between the engine and firewall, this is behind the engine. You will see the exhaust pipe, follow the exhaust pipe up to where it is bolted to the exhaust manifold. You will see the upstream O2 sensor screwed in there, more or less horizontally with wire connector pointed at driver side of car. Now get under the car and find the catalytic converter in the exhaust pipe, a big bulbous thing, the downstream O2 sensor will be after the converter, but before the muffler and will also have an electrical connection.

Steve, You can find information at several web sites. One is All Data but they will charge you for each individual vehicle but Auto Zone will provide most vehicles for free.

SOURCE: 2002 saturn l100 A/C wont work
ok ac system has a pressure switch that stops the compressor when freon is too low. they actually say it is ok for mobile a/c systems to lose a half pound a year. most a/c systems run on under 2 pounds of freon. so after 3 or 4 years some systems will just quit working. you are at 8 to 9 years so i would recommend you find an independant shop that will top off your a/c and see if it works again. this should not cost more that 50 to 75 bucks. If you were here that is what i would charge. I am in columbus ohio just to let you know. hope this helps and thanks for using fixya
