My Local Dodge Dealers Parts Dept. Can Not Come Up With An Exploded Illustration Of The Heat And Ac Box That Shows All (4) Door Actuators. I Need To Know Where The Blend Door Actuator Is And What Part Number It Has, So I Can Purchase One From My Local Dealer To Install My Self. The Illustrations I Get From The Dealer Show The Blend Door And Lever But Not The Actuator. Please Help. Its Beginning To Warm Up Here In Texas And The "little Lady" Wants Some A/c In My Truck.
