The first thing you want to do a try jumping power and ground directly to the motor to find out if the motor itself has burned out. That's what it sounds like happened.
If the motor turns out good, then I will get you the wiring diagram so you can troubleshoot the circuit.

thanks i have thought of this and will check but the original problem was that the fan would`nt kick in when car got hot. i kept the ac on to keep engine cool. possible fan is ded now but the sensors didn`t kick the fan on when it was working.

This is the diagnostic sequence.

We don't look anywhere else until we know the motor is good.
