Renault Scenic problems

[bansteadpaul]

The rear wiper on my 1999 Scenic is playing up. When you activate it from the steering column switch it is supposed to squirt water on the screen then the wiper blade will move back and forth 3 or 4 times then stop. For some strange reason the wiper blade just keeps going and doesn't stop for about 5 minutes. I've been told this might be the wiper relay but I've no idea where it is. I've been told it could be under the dashboard with the other fuses or under the bonnet somewhere. Please could you help as I really can't afford to take it to a garage to get it sorted out. Thanks.

Hi,

Apparently on here somewhere you can download any Renault handbook once you've registered your car. I'm sure there'll be a diagram in there somewhere. Once you know where the relay is go to a breaker's yard and pull one out of another car. I did the same with my Audi A4 and it cost me about 4 quid. I seem to remember Audi telling me a new relay was over 100 pounds, and still 40ish from my indie!

Hi. I've got the handbook that came with the car but it is quite vague about fuses and doesn't even mention relays. I've got a Haynes manual which is quite good and has wiring diagrams,etc but doesn't show where the relay that I want is and colour,etc. I'm quite happy to go to a breakers yard to get one but until I can find the correct one to replace I'm stuck. Any ideas?

Hello,

If the relays are in the fuse box (or if you know where they are) you could always take them out one at a time until you work out which one's the wipers. I'd expect no relay = no wipey.

Ha Ha yes I guess you're right there. If I remove what looks like a relay ( approx 1 inch square plastic box which comes in various colours) would that only stop the timer function or the would it stop the wiper from working completely? The front wiper is fine by the way.

Hello,

I'd expect it would stop the whole process, as you're effectively removing a part of the circuit. I could be wrong. You'll soon see when you start pulling them out anyway.

There could be other factors affecting your wipers, but the relay is a good place to start. If that doesn't do anything the motor / associated switches could be at fault. I believe there is a rest position the wipers are supposed to return to, and if they are having trouble doing so then they might continue to run. Apologies if that's vague, but i'm not really an electrical systems man (not on cars anyway).

Miles.
