Step-by-step guide to fix Honda Odyssey sliding door problems

Honda has determined that the cause is water entering connector C701, which is located behind the left rear side trim panel. This is the root cause of all the problems listed above and the Honda Odyssey sliding door problems. To fix the problem, seal the power sliding door rear pulley mount, reposition the foam block, dry connector C701, and apply dielectric grease to the connector.

You’ll need Lithium Dielectric Grease and 3M Super Silicone Sealer:

How to perform the Honda Odyssey sliding door repair

With the control unit removed, spray the outside of the vehicle around the driver’s side rear window and the center rail cover. Check for leaks inside the compartment. If you see water entering, you must seal it.

• Remove the driver’s side tail light

• Remove the two self-tapping screws holding the center rail cover in place and remove the cover below the driver’s side rear window.

• From inside the vehicle, remove three nuts holding the rear pulley mount. Move the mount away from the body. Clean and dry the surface. Then, apply the silicone sealer to the rear pulley mount where the gasket has failed.

• Reinstall the pulley mount and torque the nuts to 7.2 ft/lbs

• Remove the foam block that sits below the siding door control unit. Rotate the foam block so the original top side faces the vehicle’s body. Angle the front of the block down toward the front of the vehicle. Leave a 1” space for the connector C701.

• Disconnect connector C701 from the control unit. Dry the connector using compressed air. Then, apply lithium dielectric grease to it.

• Reassemble the connector and reinstall the sliding door control unit.

• Reinstall the trim and the center rail cover.
