Sliding door is not sealing properly

It is not clear whether your key fob continues to work for the passenger side door. If it does not, you should replace the battery in the fob. Such batteries are available at Wal-Mart among the batteries. If the sliding door on the driver's side makes a noise but fails to open when you use the fob, the latch motor maiy have failed. If the cable in the side door has frayed and snapped, this would explain why you can manually open and close the door but the electronics won't move the door. And if while trying to close it manually, the door fails to latch properly, this is why you get an alarm. If the latch motor, cables, or any other components are malfunctioning, it could lead to the door not closing securely, triggering the alarm. Check your latch mechanism and cables. If you can determine the malfunctioning part and replace it yourself, that is cheaper than going through the dealer.

What To Do When Your Sienna's Side Door Won't Open Or Close ' Toyota Parts Center (olathetoyota.com)

There could be several reasons why your 2007 Dodge Grand Caravan sliding door is not latching properly. Here are some possible causes:

1. Obstruction in the Door Track: Check the door track for any debris, dirt, or foreign objects that may be blocking the door from closing fully. Clean the track and remove any obstructions.
2. Broken or Misaligned Door Hinges: If the door hinges are damaged or misaligned, the door may not close properly. Inspect the hinges for any signs of damage or wear and replace them if necessary.
3. Damaged Latch or Actuator: The latch or actuator that holds the door in place may be damaged or malfunctioning, preventing the door from closing properly. Inspect the latch and actuator for any signs of damage and replace them if necessary.
4. Dead Battery: If the battery in your Dodge Grand Caravan is weak or dead, the electronic functions of the sliding door may not work properly. Check the battery and replace it if necessary.
5. Faulty Door Control Module: The sliding door may be controlled by a door control module, which may be faulty or damaged. Have the control module tested and replaced if necessary.

In any case, it's recommended that you take your vehicle to a certified mechanic or dealership to diagnose and fix the issue, especially if you are unable to get the door closed manually.

you can 'fish' a coat hanger through the door seal to press the unlock button on the armrest, or slide down along window into the door's body to attempt to manually work the locking mechanism... a slim-jim is helpful here but can be done w/ coat hanger. WARNING!: this may damage your paint or the door seal or both, or the window seal.... once in the main body of the car...trip the lever

latch has probably broke internally if you can slam door and dosent close replace latch maybe 15 dollars from a scrap yard and takes about 25 min max tools needed star screw driver and flat blade to take door panel off

On the 05 Odyssey there's a problem with the rear latch assembly(about $140each) located in the rear of each sliding door. The problem is that the latch assembly was not seal proplery and water can get into the latch cause the sliding door to act funny. Maybe replace the latch assembly will help you.

seal is fine you need to take the door apart and loosen the window track and slip it back in make sure you ajust the window frame to be snug on window
chilton make a great bible for your car thet will help it's sold at chapters

the seal is leaking and needs to be replaced,you could try rubbing it down with a lite coat of vasalene,vasaleng swells the seal...if your door is adjustable it is done on the door stop where your door latches to, looks like a u shaped peice with 2 usually star head bolts some u can loosen and move one way or the other.

Be sure it's not something that was sprayed or spilled onto your rubber noise/weather seals that line the interior of the door. Sometimes detail shops use things other than Armor All and it causes a sticky seal. Listen for a noise, if not, maybe your latch needs adjusted (the part on the door jamb, not the latch on the door). This could cause you to break a door handle in the winter.

It sounds like your linkage has disconnected from the latch. I guess your door is stuck shut. It may be possible, but really hard, but you could try to slide something into the window and try to hit the latch release. It'll be tricky though... If you do manage to pop the door open that way, you'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. Then you have to pull back the seal covering the door in order to access the linkage assembly from inside the door

iv had a few people come in with that complaint I clean inside of door and spray seal with good 100% silicone spray and spray latches with penetrating oil
