No heat in the front, but heat works in the rear.

No heat in the front, but heat works in the rear. We just bought a 2012 Dodge journey SXT two wheel drive v6. We were told that the car had a blower motor issue in the front before we bought it. I have replaced the blower motor and the resistor. Now the fans in the front work but there is no heat coming out of either side in the dash. The heat in the rear still works fine.
