Electrical Wiring Short...
... is what must be happening in my 1994 e320 sedan and I'd like to find and fix it.
The car runs well but has the tendency to show the 'lamp out' indicator on the instrument panel... but not all the time.
Example: In the daytime, with headlamps off, depressing the brake pedal will cause the radio panel lights to go out. Lift off brake pedal, radio panel lights appear full strength... In the evening, with headlamps on, the center console and radio panel lamps will dim and change as the brake pedal is used...
All the while , the 'lamp out' indicator will sometimes be on, sometimes off, seemingly without pattern.
Is there a wire harness that can be examined where the brake lamp indicator and the panel lights meet?
For what it's worth, I bought this car used and removed the aftermarket alarm and cd-changer the previous owner had installed without removing the wiring because I didn't feel confident that I wouldn't remove something important to the car. I wouldn't be suprized to find out that is the root of the problem...
Thanks for looking!

08 Lexus GS350 AWD. 08 Lexus RX350 AWD - wife's. 94 MBZ E320 - still have it.
Carefully inspect all the fuses. MBZ fuses tend to either oxidize on the connectors, or they sometimes develop a tiny crack. I've fixed a lot of wierd electrical problems with just twisting fuses in their seats.

Thank You, Arnie
I just replaced all of my fuses with new ones and my check engine light turned off! It's been a chronic annoyance that I haven't been able to fix before. I guess time will tell if this is for real.
