We are seeing a common failure in 2002 – 2009 Renault and also some Citroen and Peugeot vehicles using the same/similar window control modules (TEMIC 0675).

It can start as an intermittent window movement fault but inevitably turns into a permanent one, often leaving you with a window that’s stuck in the open position.

The control modules are prone to moisture damage and when this occurs the cars central electrical system simply shuts off power to the unit.

You can confirm this by listening for the motor when operating the window switch. If you can hear the motor trying to move the mechanism, then you have a mechanical problem; most likely a jammed actuator cable which will need to be replaced. If however you hear nothing or just the occasional click, then the window control module is most likely your problem.

We can provide and fit a remanufactured window control module or arrange the removal, repair and refitting of your existing one.

Another option we offer is to supply and fit this little gizmo:


It essentially replaces the factory fitted window control module and removes the cars central electrical system from the equation, overriding and ensuring that power gets to the window motor from the switch. This will be the most economical and probably the most robust option. The device can be fitted in less than an hour restoring your window to its former functionality. The only drawback is the loss of the “one-touch” and “total close” functions (if the vehicle is equipped).

A good battery is the heart of a modern fuel injected vehicle.

The same way an unhealthy heart can lead to all kinds of problems with other vital organs, an unhealthy battery can result in all manner of problems from failed or difficult engine starting to faults in lighting, comfort and practically every other system/module throughout the vehicle.


All cars are fitted charging systems that will keep a battery topped-up, but to get the most  out of your battery it’s good practice to give it a mains charge at least once every 6 months as this will also condition the battery, extending its life expectancy.

If you have reason to suspect your battery is getting towards the end of its life, then have it tested. A tired battery should be replaced, especially when winter is closing in!

The window/door control module is built onto the bottom of the drivers door window motor. Due to its mounting location and angle, water can penetrate the connector and cause shorting.

Once the door card is removed, The motor/control module is easily identified.

You’ll know straight away if this is the culprit as when you disconnect the plug, orange water will usually run out of the joint.


Clear evidence of moisture ingress here as yellow/green residue on multi-plug connection.

Examine the pins and receivers for corrosion damage. If you are lucky and catch the problem soon enough it may clean up with some WD40 and a toothbrush.

If you find you have no power to the ignition circuit, no warning lights on the dash etc. it would be very easy to assume that the immobiliser has developed a fault. There is an additional mega-fuse box hidden under the carpet in the drivers foot-well. One of the fuses contained therein governs power to the ignition and fuel pump circuits. It’s an absolute swine to get at and requires the drivers seat be removed. If one of the fuses has blown, check the mega-fuse box in the boot as some models often have redundant ones there that can be utilised.

5 years lost

Thanks to 000webhosts I’ve lost 5 years of helpful blogs. Articles on common faults that could have helped with the rectification of numerous faults on several makes and models of cars. This post will remain here as a warning to anyone considering the mistake of using 000webhosts. Steer Clear!
