Connect a multimeter to the positive side of the wiring to the cab blower motor. turn on the AC or fan and check if you are getting 12vdc. Check for a good ground at the black wire. If all is good then replace the cab blower motor.

Remove the engine coolant overflow tank, three bolts. You can make the check without removing anything.

with what has been said.check the fan motor for power first.after you take out the overflow tank the fan motor will come out .it does not look like it but it will .you may have to move the ac line.i also added a better ground wire for the fan motor.If you have no Freon in the system the ac clutch will not engage.

Im getting 12v from the wires so i guess ill order a new fan how do i move the ac line i cannot remove the coolant tank line does not move

pull it away by hand so that you can get the fan and motor out.It will come out.
