Door lock on a Toyota sienna none of them work how do I trouble shoot it

Sounds like something isn't right.Try to disconnect the battery for a few minutes and see if that helps.Some times the ecu gets haywired and disconnecting the battery might reset it.And if it is the original battery you might want to get it tested.

could very well be the relay for the power door and possibly the interior light relay... they are located in the fuse panel under the dash.

Have 2005 Sienna and its Driver side door was not openning. Cheap dealer fixed it himself in front of me. After opening the doors plastic assembly while sitting inside with a screw driver. Then he bent the clip towards left where the metal wire is connected. If you guys want to see what he did i would record a video and upload for you guys. Let me know at [email protected]

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