Power Window Regulator Assembly

The Power Window Regulator Assembly is a lifting device for the glass of automobtive windows. Nowadays, the lifting and lowering of many vehicle doors and windows glass is generally switched to the button-type electric lifting method with adopting the electric glass lifter. Power Window Regulator Assembly for vehicles are mostly composed of electric motors, speed reducers, guide ropes, guide plates, and glass mounting brackets. In power window system, The master switch controls the opening and closing of all door and window glass by the driver, and the sub-switches on the inner handle of each door are controlled by the passengers to open and close each door and window glass respectively, which is very convenient to operate.

How To Test Power Window Regulator Assembly？

The Power Window Regulator Assembly is the core component of the power window, which drives the window glass to rise and fall. When the ignition switch is turned on, the door and window relay contacts are closed, the electric door circuit is connected to the power supply, the master switch or sub-switch is connected to the "up" position, the current flows into the window motor, and the motor rotates to drive the regulator to make the window glass rises. The master switch or sub-switch is connected to the "down" position, the current flowing into the window motor changes direction, and the rotation direction of the motor changes accordingly, and the regulator drives the window glass to descend. When window glass rises or falls to the end, the circuit-breaker switches off for a period of time, and then returns to the on-state.

What are the common faults for regulator?

It is a common problem that the window does not rise and fall. During the detection process, the principles of fault diagnosis and elimination ideas should be followed, and all possible causes should be analyzed. When it is found that the power window does not lift, the main reasons for the failure may be:

Electric window circuit failure.
Electric window switch failure.
Motor failure.
