Nice writeup and pics!. I wonder if the flasher for the 94 Deville 4.9 is in the same location. I spent 30 minutes laying on the floorboard looking for it to no avail. Anyone ever changed a flasher on a 94 and can comment?

Do I have to be concerned with breaking any plastic or tabs when prying out the dimmer switch / gas door trunk release panel?
How difficult is to locate and remove the flasher?
How difficult is to re-connect the flasher with the metal tab to correct location?

In advance, many thanks . . .

The panel just pry's out, a little on each side at a time using a interior pry tool. The flashers easy to replace, small tabs like all the other stuff. Take your time and you won't snap them off either. Flashers under drivers side dash.
