The windshield wipers on my Barth are operated independently. Comically, the left knob operates the passenger side wiper, and the right knob the driver side. I can never get it right on the first try.

Both knobs have a "push to wash" feature. Pushing either knob sends fluid to both wipers. I'm wondering if there were originally two pumps or a two way pump? Anyone else have the same setup?

Hmm… dyslexic windshield washers?

Sounds like someone reversed the switches/harnesses. If you pull the instrument panel out you can switch them around.



On mine, both switches control the single shared washer pump also.

Thanks, Steve VW. I thought about switching them around, but two corners on my instrument panel are cracked, and I'm imagining those would need complete removal to glue back in place.

Maybe I can find some wires in a more accessible place to switch instead?

If you follow those wires from the switches down, you will see a bunch of splice connectors. If you can get to these, just swap the wires there. All are color coded: white, black, red, green.

I think you might be able to get to them if you remove the air duct and bezel below and work through the hole?

I used hombrew plastic solvent cement to weld the cracks - ½ acetone, ½ MEK.
