Repairing fresh air and heater system without fresh air blower in vehicles with air-cooled engines (from Model Year 1980 to Model Year 1982) — VW

Notes:

Fresh air is drawn into the ventilation chamber via the front panel and is routed to the outlets by means of flaps.
The warm air blower mounted on the alternator draws in warm air from the ducts behind the corner fittings on the left-hand and right-hand sides via the rear cross member. It is routed to the heater flaps and to the warm air distributor via the heat exchanger.
Instructions on how to repair the warm air blower can be found in the Workshop Manual for the Transporter in the section dealing with the electrical system, and instructions on how to repair the heat exchanger and heater flaps are in the section of the Transporter Workshop Manual on the engine.
Ventilation chamber and warm air distributor for driver`s cab do not have a fresh air blower.
Vehicles with air-cooled engines and fresh air blowers have the same heating and ventilation systems as vehicles with water-cooled engines without heat exchangers =>Page
