Great success doing this on my 1991 350 SDL ... driver side had gotten sticky (likely coffee from prior owner) ... after good cleaning, I swapped it to a back seat window switch position figuring it would get far less use there ... and, the rear window switch had probably had far less use than the passenger window.

All are still 4.0 after three years.

Be careful as you prise is apart, as there are a couple of tiny springs and various other small components ... do it in well lighted area over a clean surface - so you can find stuff if it "escapes."
