    W205 max demist button creates vibration in steering wheel?

    My W205 when the 'Max' demist button is pressed and fan on full whack, this appears to drive vibration through the steering wheel which I can feel similar to like when you run your tyres over subtle lane vibrations. Initially I thought it was the lane assistance warning me to get into...

    CLK 208 Rear demist relay

    Hi Guys, Does anyone know where the relay for the rear window demist is hidden on a 208 Clk? The light on the button comes on but I don't hear any relay click and I don't think it's working. I have looked for previous threads but can't find anything. Thanks

    W124 No demist function again

    Dont seem to be having a lot of luck lately with the 124. Following on from the new oil filter unit it needs a tensioner pulley for the serpentine belt. Not a big job but now the demist function has given up again. No air to the screen. It can be directed to face level or floor but nothing at...

    On my 211 if I push the front windscreen demist button, the dual zone temperature LCD's go off and the air is directed towards to front windscreen vents. All perfectly normal. However, if I do it manually, by turning the LH and RH dials to point to the screen , increasing both temperture...

    W203 windscreen demist boost

    On my 2006 C280 when I switch the windscreen blower / demist button on, the aircon and auto lights go out. This means that soon every window is steamed up. In every other MB the aircon has stayed on and it has routed all the blower up the windscreen. My local MB dealer seemed not to...

    Heater Fan speed low on demist

    Hi to all, trust everyone had a good Xmas. The fan speed appears very slow when windscreen de-mist is selected but, if i de-select de-mist and then select manual controls, the fan speed increases to full power. Is this normal or is there a problem?

    W203 estate side demist not working?

    Hi All, I'm just wondering whether my side heated windows are working or if they come on under different circumstances to the rear demister, as they don't appear to be warming up when I switch on the demist. Should I check a fuse? Is it on a different circuit to the rear window? I...

    W211 climate display goes blank on demist

    hi all, just noted an oddity: on my W211, with the "luxury" climate (Thermatronic, I think?) I've just realised that the climate display panel goes completely blank when I select the demist option. That's the front "air" demist, not the rear "wires" demist (which doesn't cause this). Is this...
