where is the heater control valve on a 1996 volkswagen passat
There is no Heater Control Valve. Coolant circulates through the heater core continuously. Air flow is directed through the heater core/ac evaporator in the air distribution box under the dash as required by user input. If you have no heat, there are a couple of things that could be wrong. A bad water pump, plugged up heater core, bad blend door/cable, bad Climatronic control head, or a bad actuator/motor. So, what's your question? What is the car doing/not doing that you think it should/should not do?
i'm no Ford fan, yet a Mondeo resources of a similar fee might want to be my determination. Neither Passat or A4 are fairly good, and service prices for VAG diesels are astronomical. once you're insistent on an A4 or a Passat, ?a million,00 is going to get you a finished smash till you're prepared to spend a lot of time being dissatisfied by utilising the final public of autos on the marketplace.
