Back doors wont open

The back doors on my 1999 Grand Am are stuck shut cant unlock them both electricly or manualy.Removed door panels and still cant figure it out.

P.S. Front doors work fine.

Please help !!

Sounds like somethigns off, but I doubt both back doors would have the same troubles at the saem time out of the blue....

If the child restrain switch has been armed on the rear doors, it will only open from the outside.

Also if your lock-unlock wont work electronicly then its probly a relay in the drivers side fuse box.

I was able to free up one door I guess they were rusted shut and am fighting to free up the other door got the linkage free up but cant get the door latch to pop open. Any tricks out there!!

Thanks
