Test B: A Single Power Window Is Inoperative - LH Front

PINPOINT TEST B: A SINGLE POWER WINDOW IS INOPERATIVE - LH FRONT

NOTE:
- A new LH front power window motor will not operate in one-touch up mode until initialized. Refer to Window Motor Initialization. Testing and Inspection
- The LH front power window motor must be initialized whenever a new motor is installed.
- The LH front power window motor must be de-initialized, then initialized whenever the LH front window motor is removed from the window regulator drum housing, a new window regulator is installed, a new window glass is installed, a new top run is installed or for any operation in which grease or lubricants are applied to the window regulator or glass run.

Normal Operation
Under normal operation, the LH front power window control switch receives power from the accessory delay relay through circuit CBP47 (GN/BU) and is grounded to chassis through circuit GD133 (BK). When the LH front window control switch is operated in the up position, the LH front window motor receives power through circuit CPW11 (BU/GY). When the LH front window control switch is operated in the down position, the LH front window motor receives power through circuit CPW10 (YE/VT). When the LH front window motor receives a ground signal on circuit CPW29 (VT/GY), the LH front window motor will enter one-touch up/down mode. The LH window motor receives battery power through circuit SBP01 (RD) at all times, and delayed accessory power through circuit CBP41 (BU) when the key is ON and the delayed accessory feature is active.

This pinpoint test is intended to diagnose the following:
- Fuse(s)
- Wiring, terminals or connectors
- Inoperative LH front window motor
- Inoperative LH front window control switch
- LH front window motor not initialized
