Question type: Maintenance & Repair

I have a 2002 Chevy cavalier that does not over heat
unless you run the air or sit to long. The fan is not kicking
on. Where should I start.

Start by disconnecting the coolant temperature sensor located on engine head behind alternator and run engine with sensor disconnected. Fans should run continuously. If they do, replace sensor. If fans still don't run, then we'll have to troubleshoot fans circuit

I took it off and it did nothing. I called Autozone he told me to use a paper clip and when I did that the tempature gadget went all the way up. So I am guessing it's not that. I really don't know what to to next.

That's not the sensor. Look for anotherone, the one u did is temperature indicator, there's another sensor that turns on the fans. It's called engine cooling sensor. Should be loacted o.ln the head somewhere
