Push Control System — L.H.D. MODEL
Push-control-system wiring
Components (12)
Ignition switch (ACC or ON)Fuse (blower motor branch)Fuse (intake door motor / push control)Blower motorIntake door motorDual-pressure switchThermo control ampPush control unit (REC switch, A/C switch, motor driving circuit, mode-switch contacts: DEF / F/D / FOOT / B/L / VENT)Mode door motorFan switch (OFF / 1 / 2 / 3 / 4)Blower-motor resistorIllumination feed (from illumination system)
NOTE
These switches are built into push control unit and mechanically linked to corresponding switches.
This push control system operates the intake and mode door motors to activate their corresponding doors.
