Intermittent Wipers (rain sensor) dont work

[cblx5]

Hi,

I have an 02 X5 (3.0i) and the intermittment wipers (rain sensor) do not work. If I switch them on they wipe once and then never again, unless I adjust the knob on the stalk, in which case they wipe only once again.

The wipers work perfectly in normal and fast mode, so I guess it must be my rain sensor not working. I see from searching the net that this is a relatively common problem.

Short of replacing the entire windscreen is there another known fix. I would settle for just a single 'slow' speed, as normal speed is actually too fast sometimes.

Any advice appreciated, it is a shame to drive such a car and not have intermittent wipers working.


Thanks
