Power Door Lock Switch: Description and Operation
Left Door Switch Operation (Lock)
When the door lock switch is moved to the LOCK position, voltage is supplied on the P35 circuit to the bus bar located inside the right door switch, lock
side. Battery voltage is passed through the switch to the P33 circuit to the door motors. Grounding is provided through the P34 circuit for both door
motors back to the right door switch. The ground is passed through the bus bar internal to the switch, UNLOCK side, to the P36 circuit. The P36 circuit
goes to the left front switch to a bus bar, internal to the switch, and then to the Z3 circuit. The Z3 circuit provides ground.
