The power sliding passenger door will not open even manually. At first it didn't want to close, but after I slammed it shut it didn't want to open. A few days later I was trying to get the door panel off so that I might try to fix the problem or at least try to know what was going on with it. By mistake I hit the button by the door (the button on the column between the passenger door and the power sliding door). I heard a noise. I tried to open the power sliding door manually and it opened, but then I was back at square one. It didn't want to close. I then tried to hold the door closed and press that same button on the column. The door is now closed but now it will not open again.

From the owner's manual:

If your vehicle has

the dual power sliding doors, both doors will have

to be reset. To reset a door, do the following:

1. Check to be sure the power sliding door is

unlocked and securely closed.

2. Turn the ignition to LOCK.

3. If the power sliding door overhead console

switch is in the override (deactivation)

position, return to the activation position.

4. Open the sliding door using the remote

keyless entry transmitter, overhead console

switch, or passenger switch. Allow the door to

travel fully open.

If the door does not travel to the fully open

position, press the overhead console switch to the

override (deactivation) position and slide the

door fully open and closed. Check for foreign

objects in the tracks. Repeat the procedure starting

with Step 1. If the door resists travel to the fully
open position, see your retailer for service.

How to replace Honda Odyssey sliding door lock actuator

Personally, "I" would access the Latch Actuator and unsnap the electrical connector.

Next use a OHMMETER to test if the COIL inside the body to assure it's good!

100% OPEN = BAD
6 OHMS (or so) =OK!

Honda Odyssey 2000 power door problems

Anthony!

The cog belt could be missing teeth or have debris in the cogs...

There is no "switch". The Sliding Doors should be manual anytime you try to open or close them. If not: then there is problem in the electronic system or the physical/mechanical side where something is jamming the door from opening or closing.

Has the door been serviced as in clean and lubricated tranck?A lot of power is not put to the opening or clsin mechanism for safety reasons

i have replaced many sliding door lock actuators on these vehicles..dealer part..mostly on passenger side sliding door..also possible you have a broken wire in door track harness..follow wiring from door into what looks like a plastic chain in door track at door opening

Try taking off the door, or spray some wd-40 on the rail. It sounds like its either not getting enough power or its getting caught on something.
