How to Detect and Fix Subaru Power Window Problems

by

Power window problems are common in Subaru vehicles and can be frustrating for owners. Detecting the issue early can save time and money. This guide will help you identify common problems and provide simple solutions to fix them.

Signs of Power Window Problems

  • The window does not respond when pressing the switch.
  • Unusual noises when operating the window.
  • The window moves slowly or gets stuck.
  • Intermittent operation or only working from one switch.
  • Visible damage or dirt around the window switch or track.

Common Causes of Power Window Failures

  • Blown fuse or relay
  • Faulty window switch
  • Damaged window motor
  • Broken or misaligned window regulator
  • Electrical wiring issues or corrosion

How to Detect the Problem

Start by inspecting the window switch for dirt or damage. Check if other windows are working, which can indicate whether the problem is with a specific switch or the entire system. Listen for sounds when pressing the switch; a clicking noise may suggest a faulty motor or relay. Examine the fuse box for blown fuses related to the power windows.

If the fuse is intact, test the window motor by removing the door panel and manually activating the motor with a 12V power source. If the motor runs smoothly, the issue may be with the switch or wiring. If not, the motor likely needs replacement.

Steps to Fix Common Problems

Here are some basic steps to repair typical power window issues:

  • Replace a blown fuse: Locate the fuse box, identify the window fuse, and replace it with one of the same amperage.
  • Change the window switch: Remove the door panel, disconnect the faulty switch, and install a new one.
  • Repair the window motor: If testing shows a faulty motor, remove and replace it with a compatible unit.
  • Fix wiring issues: Check for corrosion or broken wires and repair or replace as needed.
  • Realign the window regulator: If the window is misaligned, inspect the regulator and replace if damaged.

For complex repairs, consider consulting a professional mechanic. Regular maintenance can prevent many power window problems in Subaru vehicles.
