Re: [MBZ] Replacing combination switch E320
Clocksprings were in use with the W140s as well. They provided connections to the airbag as well as position indication for the ECU. Don’t ever take one apart, don’t ask me why. -D > On Jul 11, 2020, at 9:59 AM, Mitch Haley via Mercedes > wrote: > > On Sat, July 11, 2020 9:52 am, Meade Dillon via Mercedes wrote: >> That is the device that maintains the electrical connections (for the >> airbag, horn, and perhaps other controls mounted on the steering wheel) >> between the steering wheel and the steering column.

Re: [MBZ] Replacing combination switch E320
That is the device that maintains the electrical connections (for the airbag, horn, and perhaps other controls mounted on the steering wheel) between the steering wheel and the steering column. I don't think it has a big clockspring in it, I know it does not for my 124 cars. On my cars, it has carbon brushes that make the connection with copper rings on the underside of the steering wheel. - Max Charleston SC On Sat, Jul 11, 2020 at 9:33 AM Craig via Mercedes wrote: > On Sat, 11 Jul 2020 11:33:34 + (UTC) Robert Koziak via Mercedes > wrote: > > > One work of caution is when you reach the removal of the "clockspring" > > step be sure to cautiously keep it in the same exact position.

Re: [MBZ] Replacing combination switch E320
I just changed the combination switch on my 2004 E320 because the window wiper motor stopped working. It turned out to be a cut wire which apparently happened to quite a few vehicles. The new combination switch had a slight modification. The steering wheel does have to come off. I needed a pry bar and a little help to remove the steering wheel nut when I reached that step. There are quite a few videos on Youtube that had very helpful instructions. One work of caution is when you reach the removal of the "clockspring" step be sure to cautiously keep it in the same exact position. I thought I did but when reinstalling it made a clicking noise and the airbag SRS light came on. I needed to purchase a new clockspring to complete the job. Good luck!
