Normal Operation
Under normal operation, the LF power window motor microprocessor receives power at all times through circuit 1523 (DG) and from the accessory delay relay through circuit 194 (PK). Ground is provided at all times through circuit 57 (BK) and 875 (BK/LB). The master window control switch provides voltage input to the power window motor microprocessor through circuit 991 (TN/LB) and ground through circuit 992 (WH/BK) to operate the driver window down, and voltage input through circuit 992 (WH/BK) and ground through circuit 991 (TN/LB) to operate the driver window up. To operate the one-touch feature, the master window control switch provides a ground input to the LF power window motor microprocessor through circuit 2018 (OG/YE) in addition to the up or down request.
