Replaced pnp/neutral safety switch. All fuses good.
0v to bulb sockets
14v At both oranges and dark blue wire, 0v at light green at reverse relay while in reverse.
Have not tested voltages between switch and bcm, not sure of what wires to measure.
Radio and power windows do not work unless I rev up to 3k rpms immediately after turning the vehicle over.
Driver side door rarely unlocks from outside using fob, does not unlock when car goes into park. All other doors work perfectly fine.
Am I facing a bcm issue?
