406 instrument illumination

Search the group under '406 multi function display globe replacement' and the comment there about models is important. The advice about removing the radio worked for me but there was still a remaining trim covering the Allen screws. the Haynes manual is pretty good on this - but, as I say, it may not cover all details of later models. And my problem turned out to be not the multi-function display but the heating module.

Also the radio would not come completely clear for me - attached to the wiring loom - and I gave up.

If your query is about a different problem try a group search - and the Haynes manual. I seem to recall various posts over the years on this.

the only globe I ever managed to replace was in the clock - thanks to advice in this group.
