Where is the heater control valve on 1985 JAGUAR XJ6?

The heater control valve on a 1985 Jaguar XJ6 is located under the dashboard, on the passenger side. It's usually accessed by removing the glovebox. However, the exact location can vary slightly depending on the specific model and configuration. You'll likely find it connected to the heater hoses.

Because of its location and the potential for needing to partially disassemble the dashboard, this is generally considered a difficult job for the average DIY mechanic. It is highly recommended to consult a Jaguar XJ6 repair manual specific to the 1985 model year for detailed instructions and diagrams. These manuals often have exploded diagrams showing the exact location and how to access the valve.
