Just finished replacing both of my bulbs, boy that one in back is a bit tough to get out - tiny pliers might have helped. Thanks Ron for all the great pics. Did you actually buy that HVAC control just to get a nice picture?
I had an interesting side effect - now my temperature gauge actually allows warm air rather than producing heat only when almost all the way to hot position (it used to be more like an off/on switch). Must have been from bending it around to get to that back bulb - caused some linkages to change. I like it better now and it does feel a little different.
