Ok this has been happening for a while now....
From time to time a speaker decides to just cut out on me and randomly a few days later it likes to come back. Usually its the front left and sometimes the back left.
From what i've read the audio system on the 1991 W126's is unique to the W126 range. I cleaned the fader switch a few weeks ago but that didn't do anything (It wasn't too dirty to begin with)
Any ideas?
(Speakers are original and the Radio is the stock Becker unit.....and its going to stay that way
