I found a NOS Wiper switch on eBay, and when I put it on, I noticed that the wording is different since my old one mentions "WASH WIPE" and the new one "WIPER" only, while "WASH" is incrusted in the chrome button. Any expert specialised in the history of Buicks wiper switches of the seventies can explain ? :laugh: Next stupid topic like this one: the radio knobs.... ou:
