Please can anyone tell me how to safely remove the electrical circuit Board that is inside the Black box Regulator attached to the window winder motor on
a Renault Megan year 04.

The regulator can be easily removed by removing the small Torx screw at one end of the regulator and gently prising up the two clips and easing it out of place on motor body .

My problem is getting access to the small panel inside to clean the connections on board and examine tracks on circuit board .

The module plug on wiring harness fits into a female adaptor on motor which is removable via a couple of clips around its body .
then you can see the end of the circuit board and the pins on board .

I know these renaults let rain water or if you are washing your car the water pours into the door .
you may say how do i know this
well i removwd the speaker from drivers door and then washed my car and the water came down and wet the door trim around the speaker.

It is a disgrace to have a weather strip that is so ineffective .( yes not fit for purpose )

You would think they would have put a piece of plastic over the motor and connectors to protect it from water.
as they have a pice of plastic to deflect water over the door lock wiring plug .
its simple.

Hope some of you techie Guys have been in there and repaired the regulator and be able to advise on how to dismantle it.

yes i got into some bother when i removed the cover from the motor and the cables fell from the croves on the motor pulley .
so i just un hooked them from both sides of the motor pulley.

This way i was able to remove the motor completely from the door .
(warning )
DONT DO IT THIS WAY .
IF YOU CAN KEEP THE CABLES IN PLACE ON THE PULLEY AND PRISE THE PULLEY FROM MOTOR BODY AND PUSH IT INTO THE PLASTIC WHIT COVER AND CABLE TIE IT IN THERE so all will be kept in place .

I am just learning by my mistakes as i go along .

yes i bought a new framework with the cables attached to it and fitted it .
it has a loaded motor pulley on it already threaded and cable tied in place ready for you to attach the motor to it with longer screws and a clip for the window pane retention .or to keep it in place .

The lower long bolt on right hand side of door needs to be shortened to about 25mm long as the longer bolt binds against the new side rail frame they dont tell you this in their instructions
if you dont do this you will bend the mechanism side rail inside the door .


24/7 car parts can find suppliers for your renault window parts .

Hope this helps someone else .
These blogs are usefull if you are having problems and being ripped off by Renault agencies .
