Nissan Repair Questions? Ask a Mechanic for Answers ASAP
well the windows can be jumped power at the motors themselves. which will require you to remove the door panel, unless you want to jumper at the switch connector with a 12v source and probes.
Powering up the OBD connector is a whole different story. If the control units don't have power then your wasting your time.
you need to find out your power issue for starters. If the car has had time to dry out, then you need to see what fusible links are blown and fuses, then fix them first.
I was referring to jumping power from the master switch if you didn't want to do it at the motors.
you will obviously need an auxillary power source to give it power and ground since the vehicle has no power.
