2000 Honda Odyssey EX - the passenger side sliding door will not unlock either manually or electronically. I can hear three beeps when I try to unlock the door electronically, but the door lock does not move. I tried removing and replacing the fuses, but that didn't work. Can you please help?

I read about this issue while I was looking for a fix to mine. Try the following:

Remove fuse #13 for 30 seconds or more from the passenger side fusebox. This will reset the door and the clock.

OR

1.) Disable the power door switch on the left dashboard.
2.) Remove the power door fuses located under the front passenger leg area.
3.) Manually open and close both sliding doors.
4.) Restore the power door fuses located under the front passenger leg area.
5.) Enable the power door switch on the left dashboard.
6.) Try opening the sliding doors.

The tracks may be clean but the rollers can get damaged. I found one door with a roller entirely missing. There are several rollers on each of three brackets; top, middle, and lower. For example, the middle bracket has two rollers which rotate axially in the horizontal direction to track the side of the rail---and a vertical roller to carry the weight of the door on the bottom of the track. If any of these rollers becomes chipped, cracked or simply are missing, you will get grinding noises and bucking problems. Use a strong flashlight and check ALL of the rollers for damage.

Something similar to that was happening with our Odyssey...the beeping when you are driving whether it's ongoing or intermittent is the "safety alarm" letting you know the door is not closed. The power lock is not engaging. What I do when I get the beeping while driving is hit the Door Close button. It causes the door to attempt to engage again. To fix it...we first cleaned out the space below the side running board (kids were hiding crayons and things in there), then looked for any obstructions along the top and bottom tracks. I sprayed a lubricant along the tracks (I'd suggest the dry lube kind...I used WD40 the 1st time and had streaks of it dripping down after driving), use a lube that has a long straw to spray in small places...and spray up into the track that runs the length of the middle of the car. Manually open and shut it a few times to get the tracks lubed, then try it out.
If you press the open OR close button by remote or in the car and get nothing...no movement/no noises/no beeping...then it could be the electrical circuit itself, the signal itself may be impeded...or the motor shot. Have you tried any of these suggestions before?

P0740 Torque Converter Clutch Circuit Malfunction
The problem could be the torque converter itself or the sensor circuit for the clutch.
Best to have a Transmission Expert look at it to see if any further damage has occurred.
