Passenger sliding door

hi adjust and reline the sensor limits to the door

maybe the door latch maybe off centered

Automatic sliding doors use optical or motion detection sensors to activate their motorized opening and closing functions. These sensors are mounted over the automatic door. The sensors use either infrared or microwave technology to observe motion.------------------------------------------------------------------------------

door motor is worn out or track needs lubed or cleaned. sometimes grit gets in there and jams the tracks.

locate and replace door control module

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.

READ YOUR MANUAL. THERE IS A SEQUENCE INVOLVING REMOVING A FUSE WHICH RESETS THE ELECTRIC DOOR OPENER. IT IS DESCRIBED IN THE MANUAL. EASY TO DO ONE YOU HAVE THE BOOK IN HAND.

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?

there is a cable of wires that lay in the track under the slider they break from normal use.. the harness it fairly easy to change.. when you open the door lok in the opening you will see the harness there in black plastic

I think you have a latch issue or a latch release issue, pull the door panel and try and release the door latch, pull the latch and try to see what if anything is wrong with it, also make sure the linkage going to the latch from the release handle is hooked up or not otherwise damaged.
