Still no right side audio; am looking for another CM2191 head unit even though it was working fine in the old benz. Continuity checks are fine, seems like everything I swap from my known working OEM 93 system (active bass, 93 to a 92 - sameo) doesn't work. Which brings up another problem.

Swapped out my known good power antenna - no up or down. The antenna I removed was an aftermarket non-power unit, but luckily the previous fool (I feel like the current fool) did not butcher the wiring, everything was intact. Swapped out and hooked everything back up to the OEM power antenna as normal. I know my blue wire in the head unit is connected, so what am I looking for on the OEM antenna blue wire when the radio is turned on to raise the antenna? GND or 12V? I see neither. It's parked in the DOWN position. I swear, swapping the engine and tranny was easier than fixing the electronics. Relay??

Checked all fuses and installed the correct amperage for all positions. They were not quite correct according to the cover, but only found one blown fuse, the aux fan fuse. Swapped all relays IN the fuse box, no help. Thought I might stumble across the antenna relay by doing this, but I'm not sure where it is. Where is it? This could be the problem?

Electrical problems remaining:

1. No right side audio out.
2. Antenna parked down.
3. One power window does not work, drivers side rear.
4. No console interior lights (Vent/AC buttons, etc). Dash cluster lights are fine, cigar lighter works also.

Anything common here? Many thanks for your help guys. Can't stand it when stuff is not working as it should......
