Toyota Repair: 2001 Toyota electrical, rear hatch, light bulbs

Question
I own a 2001 Toyota Senna, about 6 months ago the dome lights stopped working, a few weeks after that door ajar warning light come on and stayed on. At the same time the electronic looks stopped working. I have checked all the obvious things, are the doors closed etc? Any ideas where to start with this?

Answer
The power door remote won't work as long as the door ajar light is on, even though all the doors are closed there may be a problem with one of the door switches including the rear hatch, make sure the dome light bulbs are good and replace if necessary, with the warning light on the dome lights should be on. Each door switch turns the dome light and the warning light on when it's grounded when the doors are opened, it's possible that one of the switches is bad and is shorted to ground all the time, check the switches one by one by removing them one at a time with all other doors closed, disconnect the wire, the one that has the problem will turn the warning light off when disconnected.
