Is the voltage greater than 11 volts?

Yes	GO to L2.
No	VERIFY BCM fuse 1 (30A) is OK. If OK, REPAIR the circuit. If not OK, REFER to the OEM ELECTRICAL WIRING DIAGRAM INTRODUCTION to identify the possible causes of the circuit short. DE-INITIALIZE, then INITIALIZE the LH front window motor. Refer to Window Motor Initialization .

L2 CHECK THE LH FRONT WINDOW MOTOR DELAYED ACCESSORY FEED

Measure:

Positive Lead	Measurement / Action	Negative Lead

Is the voltage greater than 11 volts?

Yes	GO to L3.
No	VERIFY BCM fuse 32 (15A) is OK. If OK, REPAIR the circuit. If not OK, REFER to the OEM ELECTRICAL WIRING DIAGRAM INTRODUCTION to identify the possible causes of the circuit short. DE-INITIALIZE, then INITIALIZE the LH front window motor. Refer to Window Motor Initialization .

L3 CHECK THE LH FRONT WINDOW MOTOR GROUND

Measure:

Positive Lead	Measurement / Action	Negative Lead

Is the resistance less than 3 ohms?

Yes	GO to L4.
No	REPAIR the circuit. DE-INITIALIZE, then INITIALIZE the LH front window motor. Refer to Window Motor Initialization .

L4 CHECK THE VOLTAGE SIGNAL FROM THE LH FRONT WINDOW CONTROL SWITCH

While pressing and releasing the LH front window control switch, measure:
