With this relay, you can add a programmable, variable intermittent feature to a Vanagon that only has a fixed interval, or even no intermittent feature. If you already have the fixed interval feature, simply remove your #19 wiper relay and put this one in. 

If you have no intermittent feature, you can remove a small tab in the stalk to allow the switch to go down to the intermittent position. It's covered in the Bentley manual, or I can show you how. 

It works this way- turn your wiper on to intermittent, then immediately off. Decide how long you want the delay. Turn it back on to intermittent when the desired interval has passed. The system now remembers that interval until you change it.

$15.50 including shipping to the U.S. I have several. Send me an e-mail if you are interested.
