Re: power door locks not working
The driver's door actuator is wired, independent of the other three......the other three actuators are in parallel, and share the same ground and power(the liftgate actuator, is also in parallel)....thus, you can program the door locks, three ways: all unlock when put in park, only the driver's unlock when put in park, or none of them unlock.....
You can can disconnect the BCM harness(es), and jumper the proper circuits to prove there is nothing wrong with the parallel circuit.....
Unfortunately, a similar BCM can't be taken out of another vehicle and used.......the VIN of your vehicle has to be programmed into it, and also the options of the vehicle......
Actually, replacing the alternator is not that hard.....it just takes a few extra moves to get it out.......not sure what you are talking about with the voltage regulator.......that is part of the alternator.....since you replaced the alternator, the regulator was in the new alternator.....$700 is too high for just replacing an alternator.....not sure if you were talking about the current sensor.....
