Help !!

Hello, all, I'm new here and this board is great.
I have a 93 3.1L Corsica.
The problem is that the fan works when the engine gets too warm but does not come on when the a/c is on.
It's a problem because the engine overheats.
What's going on?
Thanks guys.

You might have a bad fan control switch or you have fault in whatever turns the fan on when the A/C is cycled.

Check the fan circuit using a wiring diagram. I would start with the radiator fan or temperature switch turning on the fan.

Check the links/posts in my signature file for some ideas.

There's a separate A/C relay for the fan. Replace it. Costs about $20.
