2006 Berlingo BSI/wiper trouble?

[krish]

Hi all! I was hoping someone might be able to shine some light on a problem I'm having with my 1.4 petrol 2006 model that's got me a little stomped. Everything works fine mechanically except when I try to use the wipers they only work intermittently. At the same time, or sometimes triggered by my using the wipers, the brake warning light comes on and stays on most of the time even though they're working fine and recently serviced. I've done all the usual things that I'm aware of like resetting the BSI, checking the handbrake sensor etc. but it's still there. I'm thinking it's something to do with the BSI but is there something I can easily do to check or do I need to send it away for a diagnostic? Has anyone got any experience of this sort of thing happening? Any advice would be greatly appreciated! Thanks.

Hi Krish welcome to the forum your problem could be in the wiper stalk or in the BSI unit. Have you ever cleared the scuttle out under the wiper arms, the drainage holes get blocked up by years of dirt and leaves so water doesnt drain away. The water then builds up and then finds its way down the loom into the bsi causing all sorts of weird electrical problems. Clear the bottom of the wings to by the doors as this is where the water runs out. Some on here have taken the bsi apart it is like to parts sandwiched together and very carefully checked for dry joints or corrosion on the pins, but be carefull it is delicate. Have a search on the forum as I remember pictures a few years ago from someone who had done it.

Hi Tomcat3. Thank you so mcuh for your reply. I haven't tried that yet but will certainly give it a go tomorrow and update you on it as well as have another look through the archives. Thanks again!
