Sorry for an incredibly stupid question, but I need to replace the blower switch in my 1991 S15 Jimmy. The Chilton's manual I have makes no mention of how to remove the trim piece that houses the AC controls (that is, the vertical rectangle to the right of the instrument cluster). It looks like it's supposed to pop off, but it's going to take a lot of force to do that. No screws are visible anywhere in the vicinity.
Do I just muscle this thing out, or have a I missed something? It's looking like more force = buying some more new parts when the plastic breaks.
Any ideas much appreciated.
