Hi Dave,

Its will be interesting to see how Renault may or may not wriggle out of this...

Harness Routing. The area inside the door is not serviceble by Renault dealers or accesible by the owner, so the problem for routing and/or chaffing is either poor design or build.

Water in Switch. On our Scenic we have no water ingress issues in the door, windows or sunroof so the only way water can get there is either by spillage or when the door is opened and the seal drips water onto the switch. Condensation can form by differences in temperature and humidity either side of the switch. Also Scenics are renowned for condensation build up inside the car when the AC is switched off and it rains.

I have not seen a schematic of how the mirror control works on Renaults, but on our vehicles, we apply +/- to the motor to power one way and reverse it to power it the other - similar to electric windows. I'm assuming they will use a similar system hence why Power and Ground exist within a non-illuminated switch.

There is also one other possibilty the switch contacts itself either sitcking or falling apart - but this may present itself on other vehciles with the same switch, but only if the switch is mounted in the same orientation. This may happen if a build up of dust gets inside the switch.

Do you have any idea who manufactures the switch for Renault?

Ta, Mark.
