Heater Cables 1969
Short answer: For a non-A/C (cable, not vacuum) 1969, there are three color-coded cables at the controller:
- Blue tab = defrost — hooks top-left on the controller and to the defrost gate near the gas pedal.
- Black tab = heater on/off — hooks top-right on the same slide as the defrost cable (same lever); the other end hooks nearly opposite the defrost cable on the passenger side.
- Red tab = temperature — hooks on the bottom of the controller; the other end goes on top of the heater-core box behind the glovebox.
