Question about 2002 Pontiac Grand Am
It can be in one of two places, if you have an under hood fuse center it is the #12 relay in the fuse center. It may also be located under hood on the passenger side at the firewall near the heater motor.
Good luck, let me know.

i had the exact problem with my 2002 pontiac grand prix. i found a broken vacuum line that comes off the back of the engine. this vacuum line runs down the passenger side top wheel well in the engine compartment. it goes behind the battery mounts then traverses into the big wire harness just below the battery. the vacuum hose was broken there under the battery so i couldn't see it without physically tracing where it went. i took a little piece of rubber hose about the diameter of an aquarium hose and reconnected the hose. i now have cool air. you have to remember that this little vacuum hose keeps the climate control does open as well as close them depending on your hot-cold settings. this all occurs from the climate control knob inside the car. hope this helps. a real easy fix too...........phil

SOURCE: 2002 malibu runs hot.
Sounds like you have a faulty head gasket or maybe a cracked head.This can cause overheating and the check engine light to come on.The code for the o2 sensor is probably caused by coolant getting into the exhaust system and coating the sensor.The coolant fan may work but it cannot remove enough heat from the rad to make the engine cool off.Try some engine coolant stop leak to see if it will help.This maybe only a temperary fix.Let me know if you need more.MOE
