I poked around and came up with this... Price is not bad at all,,,, Looks pretty simple to put in and operate with practice...... Has anybody heard of it???? https://www.revolutionelectronics.com/Products/intermittent-wiper-module/
Found this also.... looks they have kits for hidden wipers also..... Price is a tad bit higher..... https://www.speedwaymotors.com/Detr...Speed-Wiper-Kit-66-Chevy-Chevelle,510254.html
Actually the hiding one is here: https://www.revolutionelectronics.com/Products/gm-hiding-wiper-intermitten/ Very cool item. I like the fact that it uses the original controls. I guess I am already in the habit of being my own intermittent wiper switch. Maybe someday when I get some big projects finished on the car... Thanks!
Dear Bob, and V-8 Buick fans of "singing in the rain . . . . " Thanks for posting this. I already had upgraded my wagon to the Detroit Speed wiper system and I'll probably stick with that solution. But this does look very interesting. Edouard
Look for this cool option (option code K6) in cars in a scrap yard and use it in your car with hidden wipers: This was an option on big cars with a column shifter in the first half of the 70's, it came with it's own mini brochure:
I just recently found this thread. Has anybody had any experience with Co;e-Hersee switches, part no 75600-02 ? It has the intermittent feature built into the switch itself. Turn the knob for on/of /intermittent adjustment. Push for washer. It says it needs a signal for park from the motor. Once I figure out how to wire one up I plan on on posting it up.
