Hi guys, the light bulb for the speedo on my 2975 fleetwood is out... I looked in my 1974/75 shop manua how to replace the bulbl but it seems that it’s not in there :-(.
Do I need to remove the whole dash or is there a easy way?

Many Thanks, Ramon

Access to the instrument panel cluster bulbs is from above.  Remove the center section of the instrument pad, the part that contains the AC vents. Start by removing each of the four AC vents.  Three of the four AC vents have a nut threaded to a stud inside, the ones at each end, and one of the center vents, but I don't remember which.  The center pad section slides backward to clear the studs and can be removed.  After sliding rearward, be careful to disconnect the two-way connector at the map lamp to avoid breakage, or better yet, remove the two screws holding the map lamp and just allow it to hang by its wiring while you are working. Unplug the wiper/washer switch. With the center pad removed, you can reach over the instrument cluster, and under the top pad, to twist the socket/bulb assembly to remove, and change the bulb.  If memory serves, these are type "194" bulbs.  There is a bulb chart near the back of the owner's manual that will confirm the bulb usage.

It’s the center right a/c outlet along with both outboard outlets that need removal

I'm thinking the 75 model might be the same as the 76 . If so here is the service manual page from the 76 manual. Globes are #161 in black socket and #194 in grey socket.
