For the past week or so, I've been having some trouble with the electrical systems in my CL500. For starters, the SOS light up in the OCP and the two call buttons in the center console are flickering when the car is on. Not flashing, like on time, they're just sorta flickering. Sometimes when I start it in the morning, there will be all the standard warnings you get when you remove the battery (Brake system, ABS, ESP) and I'll have to go lock to lock a few times to reset those. Sometimes, the car will start, fire up, and then the engine will quit. I have checked the battery, and it's holding 13+V pretty well while the car is running, and 11.9V or so when the car is off, so it shouldn't be a battery issue.
Now though, the problem has become slightly more immediate. My ESL (checking with DAS) says it didn't receive the start enable from the EIS and so it's locked me in park. As well, the remote isn't working to lock or unlock the doors. The windows are doing weird things too, forgetting to close after I shut the door or whatever.
Overall, it sounds as though I've got an issue somewhere in a wiring harness, or maybe a ground? Where should I look first?
Thanks!
