I Have 2000 Dodge RAM 1500 5.2 liter, and just had heater core, and AC evap replaced, heater lines, and radiator checked good, however No heat. Blower blows air fine from all places, like floor vents, defrost vents, and upper front vents, however no heat. AC works great. The temp. control has muliple colored vacuum lines that lead down to a connection, that routes to various actuators, however they all are connected, so not sure if its vaccum source in the engine compartment, or some other issue inside the cab. Any help would be appreated.
There is a actuator on the right side of your leg while sitting in the drivers seat under the dash. It has a plastic rod for actuation manually actuate this diverter and should be the problem.
