How to Troubleshoot: Volkswagen EOS Rear Window Not Working

Your Volkswagen EOS rear window is an important safety feature. It allows you to see behind you while you’re backing up, and it can also help to keep your car cool in the summer. If your rear window isn’t working, it can be a major inconvenience.

There are a few different things that could be causing your rear window not to work. In this article, we’ll walk you through the steps to troubleshoot the problem and get your rear window working again.

Step 1: Check the fuse

The first thing you should do is check the fuse for the rear window. The fuse box is located in the engine compartment. The fuse for the rear window is usually labeled RR Window.

To check the fuse, remove the fuse from the fuse box and look for a break in the metal strip. If the fuse is broken, you’ll need to replace it with a new fuse that has the same amperage rating.

Step 2: Check the wiring

Once you’ve checked the fuse, you’ll need to check the wiring for the rear window. The wiring for the rear window is located in the door panel.

To check the wiring, you’ll need to remove the door panel. Once the door panel is removed, you can inspect the wiring for any damage. Look for loose or damaged wires, and look for wires that are touching each other.

If you find any damage to the wiring, you’ll need to repair the damage before you can continue troubleshooting the problem.

Step 3: Check the motor

If the fuse and wiring are good, the next thing you’ll need to check is the motor. The motor for the rear window is located in the door panel.

To check the motor, you’ll need to remove the door panel. Once the door panel is removed, you can access the motor.

To test the motor, you can connect a 12-volt battery to the motor terminals. If the motor turns on, the motor is good. If the motor doesn’t turn on, the motor is bad and will need to be replaced.

Step 4: Check the switch

If the fuse, wiring, and motor are all good, the next thing you’ll need to check is the switch. The switch for the rear window is located on the driver’s door.

To check the switch, you can disconnect the switch from the wiring harness. Once the switch is disconnected, you can use a multimeter to test the switch.

To test the switch, you’ll need to set your multimeter to the ohms setting. Then, connect one multimeter lead to the A terminal on the switch and the other multimeter lead to the B terminal on the switch.

If the switch is good, the multimeter should read 0 ohms. If the multimeter reads infinite ohms, the switch is bad and will need to be replaced.

Step 5: Replace the rear window

If you’ve checked all of the above and the rear window still isn’t working, the last thing you can do is replace the rear window.

To replace the rear window, you’ll need to remove the old window and install a new window. You can find instructions on how to replace a rear window in your Volkswagen EOS owner’s manual.

Conclusion

Troubleshooting a rear window that isn’t working can be a bit of a challenge, but it’s definitely doable. By following the steps in this article, you should be able to get your rear window working again in no time.
