Is it possible to replace the button faces on the climate control panel? Prior owner seems to have worn out the off, low fan speed buttons, scratching through the black button and exposing the white plastic underneath. If not possible, I see complete climate control panel units for sale on eBay, a common listing has the unit fitting 1991-1996 LC models, I have a 1997, was there something special or different for the 97 model year? I don’t have auto climate control, will 1991-1996 Non- auto be a direct replacement?
