1997 elec fan prob

I've got a 1997 GT and the electric fan will not come on. I replaced the engine temp sensor and that didn't fix it. I am using a jumper wire to the battery to turn it on. Anyone know what may be wrong & how to fix it?

Check your CCRM (Constant Control Relay Module) it's located on the inner fenderwell on the passenger side. Good size box 4-6 inches square with a large plug going into it...I was able to access mine by removing my air cleaner and unbolting the bracket from the hole in the fender by the air cleaner...it houses several relays and is a common problem with the fan. Good luck, it's not easy to get to!
