I have a 2001 toyota sienna and was having a drivers side power window problem. It would occasionally not work, but if i bumbed the door panel it would work fine. Now it has completely stopped working. I checked the wiring and it seemed okay. My thinking is that the problem is the motor or the switch. Is there a way to test the motor? I don't want to buy a new motor and then find out something else is wrong. Any suggestions?

These window motors do periodically fail. Instead of trying to tinker with the motor itself, best to cut right to replacing the window motor. You can buy them online. Don't buy the cheap ones with the short warranty. Make sure you get the ones that have a multi-year or lifetime warranty, as they are usually of a higher quality. I just replaced one for my 94 Camry and the part cost $67.00 with a lifetime warranty. Make sure that the bottom of the window is securely bolted to the unit, Check to make sure the bolt made it all the way through both parts, as it is easy to overlook it if not fully secure.

The problem is in the sunvisor light. You will have to take the light assembly off and you will find wires have become disconnected.

There is an interior fuse panel located on the left side of the steering column, behind the "change compartment". You just pull it out and you will see a fuse diagram on the back. The fuse you want to replace is the fuse for the cigarette lighter, it is a 15 amp fuse and is located on the bottom right.

As far as I can tell, the owner manual makes no mention of this interior fuse panel and furthermore the actual fuse for the cigarrette lighter doesn't mention that it is connected to the clock and the power mirror.
