Hey AHCNWV1,

It sounds like the relay is stuck on which is common problem, here is a diagram to show you where there are and how to test them.

Please let me know what happens so it will help others.

Best, Ken

Thanks, it was the relay on my car cost me $35.00

My cars cooling fan runs constantly when the ac is on or when I am using defrost. I saw that I should check my realys but how do I do that?

You don't have t check anything. That is the way it is designed to operate. It is required whenever the AC compressor is engaged and it is engaged in defrost mode to remove moisture.

Cooling fans run all the time on this vehicle 10 seconds after startup A/c not on and defrost or heat not on

Here is the description of how the fans should work. If they are not working this way, then you may have a problem with one of the relays.

they cooling fan does not stop, through out driving.. thnks

Your possible causes here could be a shorted wiring, relay sticking, coolant temperature sensor out of calibration and last the computer control circuit of the fan relays-See below cooling fans circuitry
