Here's what I'd do:
- Note to self: remember we're in Britain and our N/S is everybody else's O/S in EU;
- Go back to the ****** that said me to twist the cables to twist his head off and demand for a full refund;
- Go to a reputable Renault dealer and order the proper part (or take a trip to the nearest scrappy, take the right one out from a similar car and save a bundle ).
Seriously, it won't work.
I went to a scrappy, chose another Megane Mark I (it doesn't have to be a Scenic, you won't believe how many parts are the same), after 4 hex screws to take the door card off, 2 hex bolts to take the window guide off, 5 bolts to take the whole mech out and a tenner to the scrappy, I had the proper part.
I often get spares from the scrapyard, for non-vital parts, they are more likely to fit without problems.
Also, the practice to remove the part from the scrap car is a good exercise to know how to put it back in your car.
To date, I got:
- Both rear door locks (replacement)
- N/S window actuator (repl.)
- Various engine management sensors (repl.)
- Drawer under passenger seat (add-on)
- Boot cubby holes doors (add-on)
- N/S direction indicator (repl.)
- O/S direction repeater (repl.)
- N/S tweeter (repl.)
I have spent in total £ 62. Yes, I am
that peculiar to keep an account of my expenditure at the scrappy.
A good Haynes helps a lot.
