Is it possible to add timed interval wiping to a Zafira B if it doesn't
already have it? It's an option, and mine (second hand, 1.9 SRi) doesn't
seem to have it.

If so, is it mechanical or a software mod? Probably the latter.

The manual says to push the stalk down, wait until the desired interval
is reached, then move the stalk back to the timed interval wipe position
(- -). There's no change in the interval when I push the stalk down.

I fitted the Omega relay and stalk to my Cav 3 a few years ago and was
very happy with it.

Ying tong iddle-i po!
