Renault Scenic brake light switch....easy job?

AbstractWool

Noticed that my brake lights are constantly on. Got told I probably need a new brake light switch. Is this an easy job or a garage jobby?
Would be roping in my Dad to help me!

Just a little button just above the brake pedal isn't it? When the button is out the brake lights are on (when the pedal is pushed down) and when it comes back up pushes the button and they go off?

At least that's how it worked in a Clio I used to own.

I would get yourself down into the footwell with a can of WD40 and liberally spray the switch, work the brake pedal a bit then spray again and work the pedal. With luck it may just fix it and save you the hassle of changing it. Also check that the switch hasn't worked loose or anything as any movement in it will also cause the issue you describe.

Erm don't spray WD40 on an electrical switch. If you're going to try cleaning it first, use a light dose of spray contact cleaner (from Maplin or similar).

Why not? It's safe to use on electrical items, indeed I have used it resurrect faulty electric dimmer switches in the past and I've also used it on noisy PC fans as a temporary fix until I got around to replacing them.

Really? Thats news to me and every other person who has done electronics since WD40 came into being.

Rossy.

WD = Water displacement

It's a lubricating fluid and water dispencer hense the name. It's perfectly safe to use on electrical switches.

People who say otherwise don't have a clue

Really, so you spray WD40 onto an electrical switch to clean it do you? As opposed to contact cleaner, which is designed to do just that job?

WD40 is designed to disperse water, not to clean electrical switches. To do the latter you should use Servisol.

I don't really think cleansing came in to the equation. It would act as a lubricant/penatrant in this case, which would free up the switch if it was partially seized. WD40 isn't intended to clean componants, and I'd be inclined to use Brake/Carb cleaner to "clean" certain items and never WD40.
