Check your schematic, some models change wiring to the evaporator motor.
You must have a square wave on one set of pins to the motor, chops the 13 volts in half to 6.2 as measured on a dc meter. This is a 6 pole induction motor, will not work without a square wave. If missing, the motherboard is bad. It is also best to replace the evaporator motor at the same time.
