If you have power going in and then out the other leg of the relays then check the power and grounds at the fan motors. If you have power and grounds there then you have a bad fan motor

Thank very much for your time ! I have replace the fan on the right side the smaller of the two it had no low end so I change it out and now I'm still not getting anything when I plug the module back in .just so you know I tested both fans for high and low using a 12 volt battery .the only problem was no low on the smaller of the two and as I said I swopped that out. Just till I figure this out I have hooked up a jumper wìre and switch on the smaller fan
You need a wiring diagram so you can trace back the circuits. Most of these are negative triggered. You may also have a BCM involved in the control circuits.
