I accidentally pushed too hard on the washer button and my wiper switch fell apart. Anyone know the part # or a line where I can get one. I've tried ebay but too many listings have incorrect information. Thanks

 

From Nov 73 parts book:

Grp 10.163 p/n 1993607, SWITCH wiper & washer control. 1962-65 2-speed wiper except F85, 1966 with round wiper motor except Toronado.

The 1-speed switch (doubtful on a Starfire) p/n is 1993568.

**** is Grp. 10.164, p/n 589797 **** wiper & washer control, 1965 except F85, 1966 except Toronado.

Washer pushbutton is 10.164, p/n 587715, BUTTON, washer control, 63-65 except F85, 66 all.

Other GM cars used these parts so even if the number is advertised as Buick/Chevy/Pontiac, if the group and part # is correct it will work. Just don't pay a Chevrolet price premium unless there are no others to be had.

 

Needed one of these a bit ago, hard to find they are at least 4 me it was, I thank a member here for hooking me up with one.

 

Unfortunately, that is apparently a superseded number. From the Jan 1965 parts book it's 1993567. Fits back to 1962.
And no, I don't know what the black diamond means.

 

OK, the story gets more complicated. From this Jan 1964 GM parts catalog:




Here's the Oldmobile section. Note that 1993567 fits 62-64, as shown above in the 1965 Parts Book.





Now the Buick section in that same Catalogue 205. Note the footnote on 1993567.

 

And one more, from the Borg Warner website. Note the superseded by.

 

Thanks for all the replies, so many eBay ads and websites have vague and generic information or outright incorrect fitment data. So it looks like the 1993567 was superceded by 1993607 more knowledge than I started with. much appreciated 👍

 

So do you have a 1 or 2 spd wiper? I most likely have good used. Drop a line to dead@mchsi.com

 

Bench tested switch. $40 shipped. Let me know.
