Do any of the erudite members on here know how and what, exactly, to remove to replace the illumination behind the heater/aircon control panel?

yes you have to remove the buttons from air circulation and behind the middle one there is a screw .unscrew it and then gest pull softly the panel

I have the same problem. Do the control knobs just ease off?

Thanx sicone I'll have a 'do' at it first chance I get.

yes the knobs come easy out but behind the middle one is a screw

sorry If I am in wrong part ,Have a fiat multipla year is 2000 ,can someone please tell me what bulbs are needed to illuminate the speedo .I have bought 1.2v capless but the bulb is to large is there another type . I am here :bang: now please help ,thank you

I just got some bulbs the right size and 2.2 watts from halfords. Its just replacing the two bulbs behind the heater controls that got the speedo illumination working for me

But after that the speedo lights went off again although the dashboard lights are still OK. I guess I've got a loose connection somewhere - probably in the wiring loom that I just disturbed.

Just like to add my tuppence worth with regard to accessing the heating control panel lights.

It was just with my model the tips above did not appear to apply.

I've got a "nosejob" Dynamique '05 No aircon.

To expose the top and bottom of the heating control panel.
Prise up the plastic ring around the gear lever. It has metal clasps grip it in place.
The same approach to the speedo cover. (i.e. the "space helmet")
The lip at the top allows you to grip it and persuade it to move.
It's also held by metal clasps.

Pull the middle blower knob out. Also takes a bit of persuading.
Remove the torx screw behind it.

Note that the main wiring to the fog, warning , rear window heating goes to the top of the unit and does not give you much play.
The heating control panel should now be able to be lifted from the bottom up to see the lights.
Two small push in bulbs.
286 INDICATOR DASH CAR AUTO LIGHT BULB BULBS 12V 1.2W SMALL WEDGE

The other two knobs, for the heating level and what part of car the heat goes to, can only be pulled off once the panel has been lifted, as the panel keeps these in.
Which is primarily why I gave some feedback as I nearly wrecked mine trying to pull these out.

That's mostly answered myqueery too but while poking about under there did anyone find anywhere to tap into the electrics? I want to wire in a phone/tablet charger(buck converter) as I get radio interference when I plug a charger into the cig lighter or power socket
