Anyone try this on a later model? Perhaps a 2011 or 2012?
I used my washer this morning not realizing that the headlamp washers are linked to the windshield washers if the lights are on (only once for the engine on cycle - after that they are not linked until you restart the car). Anyway, when I got to work and parked the car it looked like someone randomly scraped a bar of soap across my front quarter panels. I strive to keep my baby looking good as possible (weather permitting) and this has got to go.
Ultimately, it would be nice to be able to keep the dashboard button for when I might really need it (can't imagine when though) but I'd rather not have it at all if it is all-or-nothing.
I've only had my IS350 for about 6 weeks now and this is one of those features you don't think to ask about, especially when there is a separate button. Look up over-engineering and you'll see a picture of the Lexus headlamp washer
