    Default Centre air vent temp control - illuminated?

    Was wondering if the thumbwheel for the temperature control on the centre vents is supposed to be illuminated? Or at least the red and blue dots. Mine aren't and I seen a webpage for the E32 stating that there's a bulb for illumination, so maybe the E34 should have this too?

    Default Not all are illuminated

    I have a 1994 525 that isn't lit. If the dots look look like they are translucent then you may have a bulb. Mine are solid. I'm not sure what years are illuminated.

    An excellent description of the R&R of the bulbs from Don Gale's great web pages.

    Hope this helps.......

    I can pretty much say that they aren't illuminated because you say you have red & blue dots painted on the thumbwheel. The BMWs with the illuminated thumbwheel have a white transluscent marking on the thumbwheel.

    Yours probably looks like the one in the pic below...and center vents with thumbwheels like it are NOT illuminated:

    Thanks guys, it seems the E34 missed out on this feature which is a PITA, as I often accidentally move the vents when trying to locate the thumbwheel by feel in the dark.

    Might install a few orange LEDs on the rear-view mirror ("mood lighting" as fitted to newer models) and aim them towards the thumbwheel and OBC buttons to make up for the lack of backlighting on these items.

    My center vent temperature thumbwheel is illuminated... But it's different to the one in that pic. My red and blue dots above and below the wheel light up, but the wheel itself has no markings at all.

    Is that so complicated? Just up and down

    it's just one of the only things that the earlier cars had that the later models didn't.
