I replaced resistor nov 2019 and now I replaced the motor blower and no air comes out the front vents and I replaced the blend door actuator what can it be ?

 

With all the parts changing you've done, I would ASSUME that you started off checking fuses and for power at those components. Next item would be the ventilation control panel on the dash. BUT CHECK FOR power to operate interior fan FIRST.

 

The blend door does not control where the air comes out. It controls the temperature of the air. The mode door controls where the air comes out.

Make sure the dash vents are open. May seem obvious, but don't overlook the obvious.

 

All the fuses look good.. my sister in law bought the motor blower online dont know if that matters

 

Fuses "look good"? DO NOT ASSUME! TEST for power with a 12 volt test probe or with a volt meter to affected circuits and components. Changing parts will do NO GOOD if power or grounds are not there going thru the wiring to them.

 

Well put the old blower motor back on and now have air comong thru the front vents the new blower motor the wires were backwards so we put the old one in
