blower motor
I just replaced the heater core, A/C evaporator, and blower motor. Now my blower fan will not turn on. How should I trouble shoot the blower motor?

If you don't have 12v at the blower motor, check fuse 25 (15a) in the junction block (coil side of blower relay). Check fuse 6 (40a) in PDC (switch side of blower relay).
If you do have 12v at the blower motor and the blower motor works if you apply 12v directly to it and you're sure the relay is good, you may need to pull the heater control back out and make sure the fan switch harness is fully seated.
