before work begins)
The electric door locks inside of your car doors consist of a control switch,
the locking door latch and/or a electric control solenoid. When the control
switch is energized an electrical impulse forces the control solenoid to push or
pull the locking mechanism depending on the command selected. (lock and unlock).
Identity Door Switches and Controls

The average vehicle door has basic controls for the different functions the
door performs. Interior light and safety reflector helps illuminate the interior
of the vehicle. When the door is open the light and the reflector alert people
form a distance your door is open. The electric window switch control the
electrical power to the window motor. The motor turns a series of gears and/or
cables to power the window up and down. The electric door switch controls
electrical power to the lock solenoid actuator controlling the door to be locked
or unlocked. A manual door lock switch allows you to manually control the door
lock setting. Most manual door locks have a indictor letting you know if the
door is locked or unlocked with a red panel when unlocked. The door handle
controls to door latch which holds to door shut. Most door latches have two
stages, the first stage the door will latch but not be fully closed, the next
stage the door is fully closed.
