Honda Odysseys are notorious for having problems with the rear window motors. Fortunately they are fairly easy to repair. The problem is not the motor itself, but the connector to the motor. In this instructable I will show step by step how to remove and repair the passenger side rear window motor of a 2002 Odyssey.
Note: Thanks to member "itworks" at http://www.odyclub.com forums for information about the connector problem.
The window motor is behind this panel. To remove it you must remove the weather stripping that seals against the window. You also must loosen the lower panel. There is a hook that is attached with a screw. Use a thin blade as shown to pop the cover so you can unscrew the screw. The panel and the lower panel are snapped into place with panel clips.
The motor is behind the black duct work. The duct work is held in place by a couple of expanding clips. These may be removed by first removing the plastic screw in the center. The clips may then be pulled out. It isn't necessary to completely remove the duct, but it can be fairly difficult just to get it clear of the motor.
Unplug the connector for the wiring harness. There is a small tab that must be depressed to release the plug (see the picture with my thumbnail pressing the tab).
Removing the motor at this point is straight forward. Be careful not to drop the bolts. It won't be fun to retreive them from behind the lower panel. The lever on the motor shaft will pop out of the fixture on the window if you twist it a bit.
Remove the motor from the bracket. From here on we will be working with just the motor assembly.
