Thanks. I am not sure, I am going to check that today, but another strange issue has happened today while I had it out on two separate trips.

Today was the first time I have driven the car in awhile due to the engine issues (which is seems to be running fine for now and not stalling and running smooth). Today on the first trip out, the signal was working fine!!!

Well today the radio was turning off on its on after being on for about 3 minutes. I tried about 4 times and gave up when it turned off. Now here is where it gets weird. When I turned in the left turn signal on to switch lanes, the radio turned back on and when the signal switch was off, the radio turned back off!!! Now the signal is going crazy again and only working occasionally, but coming home on my second trip out, the radio worked fine. Not sure if it means anything, but I had to enter the radio code yesterday where I had the battery off of the car a few weeks ago to charge where it had been setting.

I get more and more confused and I pray it is nothing major. I am going to get the Mercedes tech to check that out next week... if it is the main wiring harness going out, I guess I will be trading it in on something else before it completely fails. The engine harness has already been replaced and I heard that failure of the main one inside the car is rarely an issue.
