Master Window Control Switch: Base

The LH front window control switch supplies operating voltage to both rear passenger window control switches whenever the lock-out switch is in the UNLOCK position.
The LH front window control switch supplies high current voltage and ground directly to the LH power window motor to move the window upward and downward.
When operating any passenger power window from the LH front window control switch, low current voltage signals are sent to the corresponding passenger window control switch to move the window up or down.
The LH front window control switch contains integral electronics to control the one-touch down operation of the LH front power window.
