Back doors will not unlatch.
The child lock is not on
although it wouldt matter, you can't open the doors inside or out, theyre just locked. you can't mannualy pull up on the door latch either. it won't come up.
i looked at all the fuses, solenoids and stuff, everything looked fine.
Ps. The battery is charged.
