I have a 1996 Transit (smiley front) with, I believe, a faulty heater switch. Just how much dismantling is needed to replace this? I know that the black instrument panel surround must be removed, but is it necessary to remove or disturb the entire (grey) dash? How is the switch-knob (and two similar knobs alongside) removed? Does it (do they) just pull off? They don't pull off _easily_, and I'm anxious to avoid damage. I'm hoping to replace the bulb in the clock at the same time as the heater switch. Is it _really_ necessary to do so much work simply to replace this bulb?
Modern vehicles - I despair! TIA of any reply. DB.
