Is it just me or wouldnt we all be happier WITHOUT headlamp washers? I mean, in the end, most of us keep our car clean (ie weekly wash or so at the minimum), and all the headlamp washer does is drive us crazy when it gets the fluid all over the hood and you are FORCED to wash it just so the car doesnt look good.
If and when I go back to a car with them, the first thing I will look for is a fuse or something that would turn it OFF!
It's easier to do this than you might think. In fact, you could convert the headlight washer to manual only operation.
The headlight washer is software controlled. Every 5th time you use your windshield washer, a ground signal is applied to the blue/black wire that goes to pin 9 of your headlamp washer module. To disable the headlight washer completely, snip the wire. To make it manually controlled, cut the wire and reroute it through a switch. Pin 8 (brown wire) on the washer module is the ground, so you can use a momentary contact switch to short these two pins together.
You could even get clever about it and buy a BMW switch from the early E39 ASC control. Then you would have an "Auxiliary Squirt Control" button!
Credit for the ASC switch idea goes to Jim Cash from the Roadfly board.
