The window regulators of your car are located inside the doors. They consist of metal rails, idler pulleys and a metal seat which may contain an electric engine. The entire part is connected to the window switch or winder with which the window can be opened or closed

WINDOW REGULATOR

There are two types of window regulators:

• regulators with comfort function: opening or closing the window can be done by pressing the button just once. The engine of this kind of regulator has more than two (generally four) connectors.

• regulators without comfort function: to completely roll down your window, you’ll need to keep pressing the button. These regulators have only two connectors.

On the website of Mister-Auto you’ll find the technical details of each window regulator on the product description.

HOW TO CHOOSE THE RIGHT WINDOW REGULATOR?

• If you press the button, the window rolls down unusually slowly and when rolling up, it doesn’t close completely but rolls back down instead.

• The window rolls up and down

normally but makes cracking noises when moving.

• The window doesn’t roll down but falls down.

WHEN IS IT LIKELY I HAVE A PROBLEM WITH MY REGULATORS?

TIPS FROM MISTER-AUTO

• I t i s essen t ia l to thoroughly grease your new window

regulator prior to its installation. Ensure you

have greased the pulleys and rails as well. This will pay

off in the longevity of your new regulator.

• Please note : if your car has window regulators with a comfort function, they must be replaced by those as well. By the same token, if you don’t have regulators with comfort function, you cannot install those. Instead, you must buy new window regulators without a comfort function.

• At Mister-Auto, a new window regulator will cost you about £120. whereas you will easily pay twice as much at your local dealer.

• Window regulators wi th a comfort function often need to be reinitialised. Closely follow the instructions that come with your new part to activate this function.

CHANGING YOUR WINDOW REGULATOR IN 13 EASY STEPS

Check whether your window switch still works properly. This can easily be done by taking the switch out with a plain slot screwdriver. Use a voltmeter to check if the electricity flows through. If your voltmeter indicates a number close to 0, the window switch is fine, if it shows a value much higher than 0, it has broken down.

Take the window regulator out of the door via the largest hole that you’ve got. You’ll probably have to push it right in before you can free it and lift it out. Take good care to look at the way in which it sat in the door so that you can insert the new regulator in the same way.

Compare the two window regulators. If they don’t have the same shape or colour, no need to panic, that’s fine. However, you do need to make sure both regulators have the same number of wire connectors and assembly holes.

Thoroughly grease the rails and pulleys of the new window regulator, even if it has been greased already.

Use a considerable amount of Sellotape to attach the window to the doorframe to prevent it from falling down when you remove the regulator.
