Windows: Description and Operation

INTRODUCTION
The window lift motors are of the permanent magnet type. A battery positive and negative connection to either of the two motor terminals will cause the motor to rotate in one direction. Reversing current through these same two connections will cause the motor to rotate in the opposite direction.

Each individual motor is grounded through the master switch.

NOTE: This information covers both Left-Hand Drive (LHD) and Right-Hand Drive (RHD) versions of this model. Whenever required and feasible, the RHD versions of affected vehicle components have been constructed as mirror-image of the LHD versions. While most of the illustrations used represent only the LHD version, the diagnostic and service procedures outlined can generally be applied to either version. Exceptions to this rule have been clearly identified as LHD, RHD, or Export if a special illustration or procedure is required.

CIRCUIT OPERATION
The power window system is supplied power from the 30 Amp circuit breaker located behind the fuse block. Power for the circuit breaker is supplied on circuit A22 from the ignition switch. This circuit is HOT when the ignition switch is in the RUN position.

Power for the A22 circuit is supplied by the A2 circuit which is HOT at all times and protected by a 40 Amp fuse located in the Power Distribution Center (PDC). The A22 is spliced and supplies power for the fuses that protect the Airbag, A/C-Heater blower motor, turn signals, and the heated rear window.

Circuit F21 connects, from the circuit breaker, to both window switches. This is the feed for the switches. Both switches use a BUS bar to provide power for the different functions of the switch.

The ground path for the system is through master window switch on the Z8 circuit. The grounding point is located at the instrument panel left center support brace.
