Could be bad motor, loose connection, broken wire
A few things to try before you bring it in to the dealer:• lube up the tracks of the window with WD40 or some other lubricant
• while holding the switch down, bang with your fist on the inside of the door panel [lower to middle area] If none of the above fix the problem:
• to determine if it is the motor or the switch, try opening the door so the cabin light is illuminated, then hold down the switch - if the cabin light dims, it's probably the motor, if the cabin light does not dim, it's probably the switch • check for parts online or near your place of residence
• refer to a guide on how to fix the problem
To close the back vent window on a 2018 Dodge Grand Caravan, locate the window control switches on the driver's side door or the rear passenger doors. Press the switch upward to close the vent window. If the window is stuck or not responding, check for any obstructions and ensure the vehicle's battery is functioning properly. If issues persist, consult the owner's manual for troubleshooting or seek assistance from a professional.
In most cars the passenger seat has a main control also. Try using that.
Check the window fuses. They are located underneath the driver side kick panel. If the fuses are blown the windows will not work.
I would check the switches first then check the window motor for passengers side.
you probably need to clean and re-grease the window motor

One can get a new Caravan Window by going to the company that made the caravan and asking them whether they will either fix a new caravan window, or whether they will just provide the part. One can also go to an online site such as eBay Motors, and Auto Parts Warehouse.
Go to a MECANAIC...
Before you try anything else,make sure the window lock switch on the driver side control is not turned off !
yes
no
Maybe its your driver-side window regulator that stopped working.
