Front and rear washers

[Drew]

Hi guys, haven’t been on for ages, silly busy with work and planned house move. We’ve got a problem with the front and rear screen washers on the wife’s 2003 Berlingo, they normally work fine but now and again when you lift the stalk to opperate the front washer the rear one only works. It’s got a twin outlet single pump which is fitted correctly and pumps fine just not where you want it to. Thanks in advance.

There is usually a change over relay on these single pump systems that packs up. I assume it's the same on the Berlingo.
