My 91 190E Radio doesn't produce any sound through any of the left speakers, front or back. Went from working well to low volume, to no sound in a couple of weeks. I was thinking it must be a connection to the left channel at the radio. Any ideas from someone with experience with a similar problem? The radio is the stock MB with a cassette. Speakers don't work with the cassette either. If I remove the radio to check the connections, what precautions do I need to take with the alarm?
Thanks in advance for your help.

Way don't you pull the radio out switch left speker wire connector to right side see if works.
By the way what year the vehicle is???? :-)

Its a 91. Any suggestion as to why my signature doesn't show up. It's in my profile, but not on my posting.
I'll pull it out and switch the wires as you suggest.
Thanks
