Here's a list of the problems I am having. Could they all be related, or do they sound like separate issues?

1. Nothing at startup, but Service Brake System with both ABS and BRAKE lights come on after driving a few minutes. No faults when doing a diagnostic test.
2. Driver door power lock does not work but all other locks work.
3. After turning off and opening driver door, instrument panel lights remain on, but go off as expected when another door is opened.
4. Left Rear Door Ajar warning/dome lights don't turn off.
5. Fan settings can be changed from floorboard to defrost, etc no problem, but fan doesn't blow on power 4.
6. Radio and fan: some lights work and some lights don't.

1 what are you using to checkk for codes. abs faults are chassis codes so a simply code reader won't access these codes.
2 if there is power and grd to the lock..the lock actuator is bad
3 wiring in the door may be broken. this may also be the case for fault #2. pull back the rubber loom in the door a-pillar. the wires flex when the door is opened and the movement breaks the wires after years of flexing
4 possible door lock or wiring. door ajar sense is part of the door lock actuator
5 bad blower resistor
6 blown led lights in the radio and hvac module.

separate issues. Tech2 nailed it.

#1 is a common issue. Bad ground from wiring harness to frame. Right under where you sit.

Just the basic code reader, so that explains it.
I'll check the wiring and if ok, get new door lock assemblies. Thanks so much for the feedback!
