The radiator fans are not turning on, car shuts off when it gets hot?

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?

This sounds like a different issue which we need to start a new thread for, I am glad you got the fans fixed. Please post your new question here, you must be logged in.
