Learning how to fix a window regulator can help you save a bad situation. That’s because car windows can fail at any time, even when on the move. Many motorists also choose to repair their car windows themselves. If you’re one of them, keep reading for a DIY repair procedure. If not, you may skip to the last section for a breakdown of the window regulator repair cost. But it’s not always that you’ll be able to repair a car window, so will start by looking at the problems that can be fixed.

When to Choose Window Regulator Repair

Before the car window regulator repair steps, it’s important that you understand situations that allow that. You can only opt for repair if the problem is fixable. These include broken but replaceable parts such as cables, clips, gears, or even a burned out motor. Dirty window channels, too, that prevent the smooth window movement.

In some instances, the window regulator itself is not damaged and the problem may be other parts such as burned relay, blown fuse, or bad wires. Sometimes even the window regulator switch or crank. The repair process allows you to diagnose these issues, saving you replacement expenses.

There are other reasons why you may opt for window regulator repair, such constrained budget or when you cannot source the specific part on time. In all these situations, you should confirm that the problem is repairable. Doing so helps you avoid unnecessary tasks. Without further ado, here is how to fix a window regulator.

Window Regulator Repair Steps

The window regulator on your car is connected to several parts, especially if it’s the powered type. During repair, you need to check the entire system including the wiring and associated components. These steps explain how to fix a window regulator in most cars.

Step 1 Test Window Regulator Switch

A faulty switch often causes bad window regulator symptoms. Start by testing it. For that, you need your digital multimeter. Pry open the switch and door panels to gain access to the motor connector. Using the multimeter probes, check if the switch is passing current. Here is how to do it:

  • Detach the window motor connector
  • Connect the millimeter probes to the connector to measure voltage
  • Push the window switch to move the window up and down
  • The multimeter should read 12V then -12 as the polarity changes. This indicates a working switch
  • If there’s no voltage, the switch is bad and needs replacing, or the wiring upstream is compromised

Step 2 Test Window Regulator Motor

The window motor fails if it burns out, often due to overheating. A worn motor will also cause window regulator problems. When that happens, your car window will not work at all- or works but weakly. Having tested the switch, we can now proceed to the motor. Here is how to test a window regulator motor:

  • Start by back probing (check video) the motor connector to test for voltage when you press the switch. If the connection is analogue, it will have two wires and easy to test. Digital connections are multi-wired and may be difficult to diagnose
  • If there’s power reaching the motor, it means the motor is the problem
  • Confirm the window motor problem by powering it directly. For that, use your jumper wires to connect the battery voltage to the motor terminals
  • The motor must spin. If it doesn’t, replace it or the entire window regulator mechanism. It depends on if the motor is built to the mechanism or separate

Step 3 Inspect the Window Regulator Assembly

There are instances where the switch and motor are in good condition but the window regulator lifting mechanism broken. Some of the things that can cause that to happen include broken or worn parts gears and pulleys or rollers, worn, snapped or tangled cable, and more.

Being a mechanical assembly, most of these window regulator faults are diagnosable just by looking. A visual examination will reveal rusted parts, for example, dried grease, or broken and bent parts. Here is how to fix a window regulator assembly that’s not working.

  • Secure the glass to prevent it from falling when you remove the window regulator rivets or bolts. You may use suction cupspainter’s tape or any other tape that may serve the required function
  • Take out the fasteners that hold the window regulator assembly in place, then gently slide it out through the opening on the door frame
  • Spread the assembly on a flat surface and where there is sufficient lighting. Clean and check it for signs of damage such as rust or corrosion, dried lubricant, worn or broken parts, tangled, loose, frayed, or snapped cables, and more.
  • If using window regulator repair kit, you will have parts to replace worn or broken components. You may also purchase the replaceable parts separately but that would be costly.
  • If you suspect excessive window regulator damage, consider installing a new mechanism. Sometimes, the repair cost offers little financial savings. Depending on the type of damage, make the right choice.
  • Complete the window regulator repair steps by greasing the assembly. Use the recommended type of grease for window regulator parts, such as silicone grease, to achieve the best results.

Step 4 Install Window Regulator

Reinstall the repaired window regulator by sliding it into the door space and bolting it in place. If the motor is separate replace it too. Test the assembly to see if it’s working. If it doesn’t, the mechanism could be too worn for repair. Instead, replace it with a new one.

Car window regulator repair involves more than inspecting the mechanism or testing the motor and switch. There are times when these parts are in good condition but you cannot get the window to move. That happens as a result of bad wiring, blown fuse, and damaged relay.

Unless you replace these parts, your car power window will not work. Note that the location of the components varies across different vehicles, and you might need your car’s manual. Check the parts using a multimeter and visual inspection then replace the faulty ones.

How much does it Cost to fix a Window Regulator?

If you do not know how to fix a window regulator, the only other option is to take your car to a mechanic. Charges vary from one repair shop to another. The car window regulator repair cost also depends on your type of car or regulator mechanism. If you own a high-end car, for example, the cost will be higher than usual.
