Yes, the coolant sensor does run the cooling fan via the ECM the IPDM I would check the fusible link K and L in the main fuse panel under the hood in case one of the fan motors has shorted out and popped the link. Also try to turn the fan motors by hand (engine off) to see if they seem to spin freely if not, they need to be replaced. Here is the link location so you can check it out and the wiring diagrams for the fan motors so you can see how the system works. I have also included the location of the coolant temperature sensor so you can swap it out. If the fan motors are okay, I have to tell you I have seen the IPDM go out and cause this issue of the fans not working.
