This 2014 Dodge Ram 5500 Truck came in the shop with the Air conditioner not blowing good. The Longer it runs, then worse it got. We Removed and replaced Heater Core and evaporator core case, cleaned dirt from heater core and evaporator core and install door kit and cabin air filter. We also did a Air conditioner vac and recharge which includes: vacuum system and recharge. (does not include refrigerant) Air Blows GREAT now!!!!!
