Angry Still looking for help - 91 300se electrical and heat

Still looking for help on the interior driver door problem. Interior lights will not turn on when the door opens. Passenger side works fine. Also, I notice the rear heat vent only blows cold air, even when the heater is on. Is that right??

Drivers side door switch operates thru the WARNING buzzer. It is under the drivers under dash panel.
Rear seat vent is either fresh air or A/C, no heat. Heater ducts are under the front seats.

My 91 300SE blows cold air from the rear vent even when the heater's on and no air blows from the center dash vents. I was wondering why my kid was complaining that he was cold when I have the heat turned up. I guess this is normal.

91 300se Door light problem

Thank to MB DOC and others for the help. It appears this is a job for a good tech. On the 300SE do you need to remove the cluster display to get to this diode for replacement?

Thanks again.
