cant open rear door or window
OK , so do you want help and this thing is 12 years old and things break.
Carry a spring loaded center punch if the other windows fail and you need emergency egress.
Does the door unlock and open manually? If it does but it’s not responding to the switch or the remote you probably have a broken wire running from the frame to the door.
I have the spring loaded punch with a seat belt cutter readily available.
Are the child protection locks that prevent the rear doors and windows from opening engaged?
You can remove one of the headrest and use the two poles to break the windows in a emergency.They have a pointed tip made for this purpose.
Good thing to know.
