    My SLK has a problem and it would appear that there is a unit behind the headlight switch which has failed - the AA man said it could be a fault following a battery change a couple of months ago. Total newbie please if you could support me with advice for a potential for DIY assessment / resolve. Have had to disconnect battery as the burning smell just had to be indicating secondary damage if some kind and the lights wouldn't switch off when ignition set to off.

    All advice and help really appreciated

    Why not remove the lick panel under the dash,,, you can then see if it is the actual light switch that is the problem

    It would appear that in order to remove the actual switch unit I will have to remove the steering wheel. There is no visible melted plastic or anything anywhere but the smell was strong.

    Thanks for your help and Happy New Year too!

    With the panel under the dash off you could feel what was getting hot, that is the important bit, plastic can turn to carbon when arcing has taken place.

    Once you know for sure what is getting hot I can give you the work sheet for changing the switch or what ever it is thats wrong.

    I am opting for just takin it to pieces and having a look at the components within that block - could you direct me to worksheets for that? Including the steering wheel removal - really appreciate your swift replies.
