The Heater fan is powered by the 15A 'W' fuse in the Fuse Box. The 'W' fuse is for Wiper/Washer/Heater.

Heater resistor (outside view)
Regular Wiring
When IG is on, heater fan motor is always "Hot". But the motor is not grounded until the heater switch is pulled out.
Fan switch Position No. 1 is OFF Fan switch Position No. 2 is low-speed via Resistor Fan switch Position No. 3 is high-speed bypassing Resistor
Heater wire loom with B wire and Y, YR, wires:
(the blue wire is not part of the heater circuit)
1972 USA
For 1972 USA models, the heater and switch operated differently. Now the motor fan is directly connected to Ground via B wire, and HOT is switched via a new type switch.
Fan
- B: ground
- ?: High speed
- ?: Low speed
Switch
- LW: 12V from Fuse Box "W" (Wiper/Washer/Heater) via LR wire
- ?: High speed
- ?: Low speed
Illuminated
Some 1200s have illuminated dashboard controls, like the B210.
1973 USA
The wiring is opposite of other 1200s and also includes to lamps for illumination.
When key is at IGN, fan switch is "Hot". Position #1 is OFF. Position #2 connects to the fan resistor (in the fan enclosure) for low-speed mode. Position #3 connects directly to the motor for high-speed operation.
PROBLEM: The wiring diagram does not show how the fan Black wire is earthed.
Fan (Heater)
- B: Ground?
- n: Low speed
- n: high speed
