Where is the heater control valve on a 1995 Audi a6?

1. Locate the heater hoses. The heater hoses are two large hoses that run from the engine to the heater core. They are usually black or blue in color.

2. Follow the heater hoses to the heater control valve. The heater control valve is a small, round valve that is located in the engine compartment. It is usually made of metal and has a black plastic knob on top.

3. Turn the knob on the heater control valve to open it. This will allow hot coolant to flow through the heater core and into the passenger compartment.
