Im not sure which one is for the cooling fans.I pulled all of them and it continued to runIve currently disconnected battery and charging it directly away from my truck

You should have three separate cooling fan relays under the hood. I would remove one of them at a time to see if there is an improvement. Just a heads head, cooling fans will run for a bit with the engine turned off while the engine is hot. However, if the problem continues, there is an electrical issue that needs to be addressed.

If the fans are running when the temperature is not hot, disconnect the Powertrain Control Module and inspect connectors for corrosion and fix or clean and needed. If the fans stopped running with the PCM disconnected and there is no corrosion, replace the PCM. If they continue to run, inspect the relay center or corrosion or a shorted wire. Also check the wires from the relay center to the PCM for a short to ground or another wire. It has been a pleasure working with you. Keep in mind this is a “starting point”. We can always continue as needed at a later date or at any time. Feel free to run some tests and reply back for further assistance as needed. Glad I can help. Please let me know if you have any further questions. Thanks and have a great day!
