Toyota Repair: Sienna electric door stopped working, service bulletins, control computer

Question
Just bought 2004 Sienna a month ago. Pass.elec.door stopped working. Could problem be simple as a fuse? Are there troubleshooting steps to follow?

Answer
This is almost always due to the door control computer malfunctioning and replacing the computer normally fixes this problem, Toyota has issued several service bulletins for sliding door problems so if you can provide an email address I can mail some information, does the other side sliding door still work?
