Purpose.

To determine the operating performance characteristics of dropping, power and manual, window systems.

Foreword.

Power window system operating performance tests can be used to obtain the following data:

Travel time.

Average run current.

Peak run current (excluding motor start up).

Average stall current.

Average stall voltage.

Peak stall current.

Average run voltage.

Peak run voltage.

Peak stall force.

Plots of current and voltage vs. time.

Manual window system operating performance tests obtain data for the spindle torques required for window travel.

Applicability.

This procedure applies to all passenger cars, light duty trucks and medium duty trucks having dropping, power or manual, window systems. The procedure also applies to midgates and endgates with dropping windows.
