AUDI A4 Window regulator front and rear

Can I replace electric/manual window regulators on Audi A4 myself?

Replacement of these components on cars of this make is a simple procedure. Just follow the instructions from the vehicle manual, and you will handle it easily. Fasteners may vary on cars of different production years. Therefore, you’ll need different tools to undo them. For instance, for a second-generation car, you will need a Torx key and a Phillips screwdriver to remove the door panel.

What types of parts are installed on this model?

Usually, this model has electric regulators fitted both in the front and in the rear. They feature a small motor which moves the windows. It is activated by pressing a button mounted on the armrest. Older versions could have manual mechanisms actuated by rotating a handle mounted on the door.

How do I know when a window regulator on Audi A4 is working with malfunctions or broken?

If the problem is mechanical, the window moves jerkily or too slow. This indicates a jammed cable, soiled window tracks or worn-out gears. Sometimes, the window regulator mechanism cracks or screeches during operation. Or you can hear the motor working after you’ve turned the regulator on, but the window doesn’t move. This happens when the cable is torn. The symptom of an electrical malfunction is no reaction when you turn the device on. This problem occurs when the fuse, relay, electric motor or wiring burn out. To check them, you will need a wiring diagram for power windows, which you can find in the vehicle manual, a multimeter and a control light.

Can cold weather affect the operation of electric window regulators on my car?

Yes. This situation is familiar to many owners of this model: all works well when it’s warm outside, but when it’s cold, you can’t raise or lower the windows until the car is warmed up. Usually, this happens if a door seal has lost its tightness. If there are gaps between the seal and its mounting surface, moisture gets inside the door and settles there. When it’s cold, the moisture freezes causing the arms and cables to jam.

Can I repair window regulators on Audi A4 myself?

Yes. There are repair kits for these units, which help to replace a torn or jammed cable or pulley. You can order an electric motor, relay, button box or fuse separately. In some cases there is no need to replace faulty elements – you can simply clean and grease them.

Can I replace these components on one door only?

Yes, it is reasonable to replace only the unit which is broken or failing.

Is it possible to install the parts from different manufacturers on the doors of my car?

Yes. They only need to be of high quality and meet the vehicle’s specifications.
