How in the heck I can change the lightbulb there????
3) my check engine light still on, did not had time to drive to a MB shop. Searched for any clues. The engine is making a strange noise as well. I want to see if I can tape it and attach it here. Maybe it tells you guys something ???? Still driving the car with no issues other than a little weird shaking when the engine is running when the car stands still. Can this not be related to something specific?

I wish I could fix all those issues myself. I feel capable, I just don't know what the parts are called, where they are located and what they are there for. Pisses me off, I should study this stuff.
This sounds like the Dreaded JerryLee Lewis "Whole lotta shakin Goin On" syndrome...Kidding, but I would check the plug wire boots to see if they are securely on. I think a bad coil pack would throw a code.
What part of Florida are you in, perhaps I can recommend a decent shop.
As far as the AC is concerned, I'm having a similar, unresolved problem with the fan speeds, they seem to blow unpredictably but never when turned off. If I wiggle the speed ****, it changes so I suspect a bad speed selector switch. There is a service manual here in the forum that will help you disassemble the console to get to those switches.
