Picking the Best Window Regulator for Your Car and Learning How It Works

You have enjoyed the power window feature of your car through the years that allowed you easy control of the rolling up and down of the vehicle’s glass windows. This is thanks to the power window regulator and motor assembly that supplied the power for the window glass movements with a slight touch of your fingertips. However, excessive use will soon take a toll, and the window regulator will eventually go bad. The car window regulator repair cost can be quite expensive. However, if you have the basic knowledge and a couple of repair tools, you can save big bucks by doing the window regulator repair by yourself.

What Is a Window Regulator?

By knowing how window regulators work, you will better understand the question, “What does a window regulator do?” A window regulator is a mechanism that provides the ability to roll the vehicle’s window up and down. There are two types – the power window and the manual window regulator.

The power window regulator lets you control the opening and closing of the car’s window with a slight touch of a button. This is a significant improvement from the traditional manual window regulator, where you have to manually rotate the window crank to roll it up and down.

Every door window of the car has one regulator that controls the movement of the window glass. So, if one window fails to open, it’s possible you need a power window regulator replacement. However, your purchase should be door-specific. If you happen to buy a driver-side window regulator, that product won’t fit in the defective rear passenger-side door.

What Are Some Good Window Regulators?

You’ll come across several window regulators on the automotive store shelves and online shops. Looking for one can be quite challenging, considering that the window regulator market is something unpopular, unlike car window tints, window shades, and headlights. To make things easier for you, we’ve created a list of the top products around.

How to Pick the Best Window Regulator for Your Car 

Price is always a significant factor in shopping. However, for window regulators and motor assemblies, there are other things to look for to ensure you have the right product for the replacement of the defective one. Among the important variables are as follows.

Compatibility

Not all front passenger-side window regulators are compatible with the same side in your vehicle. Some parts are brand-specific due to size and dimensions. So, it’s important to read the fine prints and check if the aftermarket replacement window regulator that you are planning to buy is compatible with your car.

With or Without Motor

It’s easy to be deceived by the cheaper price. However, watch out as it could be a lot cheaper than a similar product because it comes without a window lift motor. If the window regulator motor is still functional, then it’s okay to get one without the motor. If the motor is defective, it’s best to buy the entire motor assembly.

Easy to Install

Not all power window regulator replacement parts are easy to install. Some products may need some special tools for the replacement and installation process. Others don’t require any special tool at all. This may not be a significant factor if you are using a professional service for the replacement. However, if you are going to do it yourself, the easy-to-install feature will be a great help.

Brand

Branding provides assurance on durability and reliability. With some brands in the window regulator market not familiar for most car owners, it’s important to check the history and reputation of the brand to ensure you are getting a premium product with the best quality.

By properly taking into account each of the above factors, nothing should go wrong with your shopping for the right power window regulator and motor assembly of your car. Moreover, we have a list of the top five products in the market to further take out the stress of shopping in an unfamiliar market.
