Morning all,

Could anybody point me in the direction on how to replace a brake light switch on a W126 please? I’m just about to go and get the part from MB.

My brake lights decided to stop working yesterday. All other lights working.

Thanks

Not had to do a switch change on this model but on most around that year it's just a clip into place. Nothing complicated and less than 2 minutes. Before you do that though, the brake lights don't share a fuse with the other lamps so check the fuse first. I think it also controls the roof lights and the cruise and maybe the tach' too.
 
This is the location of the brake light switch ..You remove the nut holding it in to remove the switch and lift it out, Screenshot 2021-08-15 at 09-39-14 Sec-1 - 42-0040 pdf.png but first remove the plug . .But you will have to adjust the switch in the bracket so the rear lights operate ,..
 
Many thanks for your help - all sorted :).
