The Datsun 1200 comes with a front windshield defroster. Nissan calls it the defroster, but in areas where it doesn't freeze it is popularly called a defogger or demister. It has two vents on top of the dashboard just under the windscreen.

Operation

For the most effective demisting, heat is suggested by the owner's manual. However in warm climates you may find that cool air can also demist the windscreen. Cracking the side window may also help.

DEFROST/DEMIST
Upper Lever: DEF position
Lower Lever: Switch pulled out (lo or high fan)

B10 Defogger

OPTION for Datsun 1000 in Australia was this rear window defogger. It is an electrically heated air-blower design. Being as it is bolted below the rear window, it could probably be used with the Datsun 1200.

Heaterless Cars

Not all 1200s came with a room heater. You can finish out the demister by:

• Install the heater package, either factory unit or a universal unit

OR

• Fit 12V electric heater and fan to the defroster nozzles. 12V hairdryers can be used.
