When you’re driving and it gets hot, it’s a great relief to turn the windows down in a matter of seconds and at the touch of a button. Power window regulators are far more convenient than their predecessors, the hand rolling window regulators. Once a luxury, power windows have become a necessity in modern vehicles. These windows feature a window regulator and motor which work to roll the window up or down at the touch of a button. However, like any other part of the car, power windows can have issues and fail. In this blog, we explore answers to the question ‘how to tell if a window motor or regulator is bad.’ We discuss bad window regulator symptoms to help you spot problems in your power windows early so you can have them fixed.

It is important to spot power window problems as soon as possible and have them fixed early. Continuing to operate with a malfunctioning window will only result in complete failure of the window regulator or motor. It may also cause failures in other parts of the car and leave your vehicle vulnerable to unauthorized individuals.

Understanding the Power Window Regulator

Power window regulators are a vital component that facilitates the movement of the car’s window. It is responsible for converting the electrical power from the window switch into mechanical motion. This allows the window to open and close smoothly. However, power window regulators can malfunction.

Common Signs of Power Window Regulator Issues

Slow or uneven movement of the window

One of the most common signs of a bad window regulator is when the window movement becomes noticeably slow or uneven. This may be the result of various factors including lack of proper lubrication, worn-out components or potential electrical issues within the power window regulator system. Over time, friction and wear can impede the smooth operation of the regulator, resulting in sluggish or uneven movement.

Unusual noises such as grinding or clicking during window operation

If you hear unusual grinding or clicking noises when operating your windows, you probably have a problem with your window regulator. The noises often stem from worn-out gears, damaged cables or misaligned components within the power window regulator. If you ignore these sounds it could lead to further damage and even complete failure of the regulator.

Window slipping down or refusing to stay in raised position

This occurs when the window slips down unexpectedly or cannot stay in a raised position. This is the result of failure of the regulator to hold the window in place. It may be the result of a broken cable, worn-out pulleys or damaged guide rails.

Inability to control the window’s movement accurately

If you’re unable to control your windows to precise movements, it may be due to a faulty switch. It may also be the result of damaged wiring or an internal issue within the regulator mechanism.

Diagnosing Power Window Regulator Problems

How do I know if my window regulator is bad? When diagnosing problems with the window, it is important to differentiate between a faulty window regulator and symptoms of bad window motor. Below, we share a step by step guide to identify problems with the window regulator.

1. Use a flashlight to inspect the window and regulator components. Look for signs of damage such as damaged pulleys or cables.
2. Use a multimeter to check if power is reaching the window regulator when the switch is activated.
3. If the window is stuck, try to move it manually by pulling up or pushing down gently on the glass.
