I have changed the blower motor and the resister and the A/C still isnt not blowing any air. I can feel the rear air is on and getting cold. So it the front blower motor. The resister is now getting super hot, like crazy hot. Now I didnt change the wiring harness but I have checked all the fuzes and inside and out are fine. What else could it be????

When you installed the blower motor did you check it if its working. If so and you've changed out the resistor-your problem is coming from the HVAC control assembly/blower switch

Ok where is that? or is it the head unit in the van... the blower motor works and the resistor has power so where is the HVAC control assembly/blower switch?
