It gets hot when I put the A/C on. The fans are not turning on and my car's been turning off when it gets hot too.

It could be the coolant temperature sensor, fuse, control relay or one of the fan motors is shorted out.

here is a guide to help go over the problem and how to fix them:

Also, I have included the cooling fan wiring diagrams so you can see how the system works and which fuses and relays to swap out. Check out the images (below). Please let us know how it goes.

Okay, I found out fans don't work, bought new ones today it was driving smoothly but it turned off at the light. The temperature didn't rise. What else can I check? Why would it turn off?
