Not to hijack this thread but my buzzer only works when passenger door is open, not driver's door. Is this correct or is something not connected? Door jamb switch operates cabin light with no issues. Car is 70 Challenger. Thanks!
The driver's side door jamb switch has two wires connected to it. One solid yellow wire runs to the rear harness that connects to the dome light. (M2B-18Y)
The second wire is yellow w/ black tracer (M6B-18Y*) that runs to a female single bullet connector for the delay light wiring sub harness. A second wire at that female connector (M6A-18Y*) continues to the 2983696 buzzer relay that is a dual wire connection at the relay terminal with the passenger's side door jamb switch wire (M6-18Y*).
Long story short,
either the left or right door when opened should make the buzzer work, if the key is in the ignition switch.
It could be as simple as the M6B-18Y* is not connected onto the door jamb switch terminal.
