Dig deep ladies. I hear people weinering about this piece a lot, well, not a whole lot, but it's either the light switch knob or the pulse wiper control on the dash. Yeah, a bit pricey, but if you want NEW GM, this is how it's done. It's like finding a later model G-body pulse wiper cover with the circuit board. Unobtanium

p/n 25501804 (listing has an extra 5 in it), ACDelco # D6338A, fit's 1980 A and E body OLDS and BUICK. Also fits 81 A body Olds, and E body Buick. WITH Pulse Wipers. According to the parts books. Not sure about the Buick parts, but I'm not very familiar with them prior to 82.

Good luck.

Fortunately when I was converting my 81' to delay I found a NOS Pontiac delay 80/81 switch for "only" $63 shipped on eBay, in 2020. I would of just rolled the dice with a used one if it was much more than that but glad I found the one I did.
