Thank you will try it and see if that will fix it

You're welcome. Hope it is an easy fix otherwise you would need to test the fans and controls etc which can be rather time consuming.

Do the fans run when A/C is turned on?

Item # 24 is the low speed whereas # 32 is the high speed fan relay. I have the schematics here for you. Go through get an understanding of the system. Note where the Engine Coolant Temperature sensor is as we might need to do some test there.

Get a test light or DVOM and we can get cracking to diagnose the problem.

The fans do not run when A/C is turned on

Since both fans are not working, lets do a simple test first.

Start engine and turn A/c on. Give both fans housing some light knocking with a mallet or anything that can produce some slight vibrations. Note if any fan comes on. If they don't, continue with next step.

You would need to test the fan motors first. Fan motors do not fail simultaneously but there is a possibility one failed and was not noted until the next one failed.

Unplug the wire connector and apply battery voltage to the Red/Orange terminal of the fan motor and ground the other terminal. If fan works, they are good. Alternatively you can test the resistance of the two terminals with an ohmmeter. No continuity indicates a failed motor.

Stop engine. Unplug the wire connector of either one cooling fan and test for battery voltage at the Red/Orange wire with engine running and A/C turned on.

If you have battery voltage, use a jumper wire to ground the Black wire and see if the other fan works.
