Does anyone know if it is possible to change the bulb without removing the instrument from the dashboard?
If RichardV6's suggestion doesn't work, then why not take out the dashboard ? Not a horrible job (mind you, mine is a later car so may differ), and a one-person job. It helps to remove the steering wheel, then after removing the screws that hold the dash in place, the dash can be lowered enough to see behind. Use the opportunity to vacuum-out the bugs and tidy-up the wiring if needed. Disconnect the battery first if you don't want to risk knowing what burning ash smells like.
