Heating System



Starting with the 85/2 model, all 944 vehicles received a new heating system.





1 Defrost switch.

2 Outside air blower switch.

3 Defrost slide switch.

4 Footwell slide switch.

5 Temperature switch.

6 Ventilation switch.

The new heating system differs from the old in that all control of the flaps is accomplished via electric control motors or by vacuum pressure.

As a special option, there is an automatic heating system with which the interior temperature can be preselected via a temperaturepreselection switch. The heating system then independently controls the interior temperature and maintains it at the preselected value, as long as the outside temperature is lower than the preselected interior temperature.

For the removal, installation, disassembly, and assembly of the heating unit, see Repair Group 87.

Several assembly parts do not apply to vehicles not having air conditioning.
