How to Protect your Window Regulator this Winter

If you live in an area with long, cold winters, you need to take extra care of your truck to make sure it can withstand the elements. One of the parts that are susceptible to damage in cold weather are the window regulators. 

What is a Window Regulator?

A window regulator is a mechanical device that controls the up-and-down movement of your truck’s windows. This part is located inside the door panel and is attached to the window glass. It consists of a series of gears and pulleys that work together to move the window up and down.

Why Does Cold Weather Affect It?

The problem with cold weather is that it can cause the gears and pulleys in the window regulator to freeze, preventing the window from moving. In some cases, the window may get stuck in the down position, and you will not be able to close it. In other cases, the window may get stuck in the up position, and you will not be able to open it. Either way, it can be a major inconvenience.

How Can I Prevent It?

You can do a few things to prevent your window regulator from freezing in cold weather.

  • First, make sure that you keep your truck’s doors closed as much as possible when it’s cold outside. This will help keep the warm air inside the cab and prevent the cold air from getting in.
  • Second, if you know that you’re going to be driving in freezing temperatures, make sure to run your heater for a few minutes before you get on the road. This will help warm up the inside of your truck and prevent the windows from fogging up.
  • Lastly, invest in a good set of winter gloves so you can still operate your truck’s windows in case it gets stuck. 

Bonus Tip

A good trick to keep your windows running smoothly year-round is to use some silicon spray around the outside window channel (where the edges of the glass sit when the windows are closed).  Spray a little on the sides and top channel.  You can use a glove to spread the spray throughout the length of the channel.  This can extend the life of your window regulator by keeping things running smoothly, especially in the winter.  Doing this a couple of times a year can really make a difference in extending the life of your regulator. Lastly, wipe down your door seals with silicon to help prevent doors from freezing shut.
