Audit monitor removal from dash in a '91 GrandVilla
I've attached a picture showing the six screw locations that need to be removed to get the monitor out. The bottom two in the front are a bit of a problem to get to. If you remove the two screws holding the heatsink/power supply to the monitor cover you can then slide it off toward the front of the coach and it will make it easier to get to the bottom screws.
The other thing I had to do was remove the screw that clamps the heater valve cable in place to give me room to get it up out of the dash.
