SUBJECT: HEATER/AIR CONDITIONING MODE SWITCH OPERATION
If the heater/air conditioning mode switch fails to operate,
first check that the vacuum check valve is fitted correctly.
The black and white plastic valve is fitted into the vacuum line
between the vacuum reservoir and engine and is to be found towards
the left front of the engine compartment.
When correctly fitted, the black side of the valve faces towards
the engine.
Please inform all personnel accordingly.
