Has anyone monkeyed with the wiper controls on their 123 and successfully converted it to have fully adjustable intermittent wipers.

Volvo once had a special relay for certain models that would enable you to set the speed of intermittent wipers. You would turn it on, then turn off at the desired wipe interval, then back on, and the wipers would wipe at the set interval.....kind of hard to adjust a little faster or slower.

Among the many features I wish my car had (tilt steering wheel??), the adjustable intermittent wipers seems realistic. Any help out there??

Thanks,

Mark
