The lever came loose. It needs be re-attached. I have had to do that manually and it requires going into the door.
Go in from another door and open it from the inside.
You have to pull the inside door panel off. Once removed, look for the door latch mechanism and pry it with a screwdriver. This will release the door.
Take inner door panel off and look inside the door and you will probably find a rod off the outside door handle.
the linkages to either the handles or the lock or both has come off. here's the kicker... you need to open the door to take of the inside door pannel to fix it. try to remove the pannel with the door closed. or a "skilled" vheicle locksmith could open it from the outside...but it's not cheap.
You can contact the company to determine the best way to fix the door. They can send the right tools or give you the information to get it to work.
A person a can open the rear door from the inside. Get into the car from another door that will open and open it from the there.
Are the switches on for the childproof door locks ? Open each back door from outside and look about 3 inches below the latching mechanism on the door and see if the levers are switched up , if so move the lever down
I suspect the rod that opens the door has come loose or broken off the door handle and is keeping the window from coming down. Take the inside door panel off and check. If needed just replace the door handle.
disconnect the battery and try to open manually from inside
The linkage may have popped off or the lever on the inside handle may be broken. Remove the inside door panel and you will probably see what happened.
Sounds like the rod came off of the door handle,remove the inside door panel and look. Most vehicles have a plastic insert that holds it in place , you might have to change it to keep it on. hope this helps.
if its a lift up handle and wont open your door most probably the rods come out of its slot inside the door
