hi
I have just changed my main illumination bulbs on 2003 mondeo dash.
Just take the 5 phillips screws out from the lower dash (under the steering column) and pull towards you to remove.
Lye on back under dash with torch, and you can just see the 2 bulb carriers, reach in, twist, remove. To replace, they were tight to twist in, so put a socket on the base of the bulb carrier, and pushed in and twisted.
Saves taking the upper dash apart and removing instrument cluster!
