Question about 2003 GMC Safari
Attempted to open both doors from inside, door handle moves, but will not relese the door. Manual functions on vechicles should always work regardless, as it is a safety feature. Power locking devices are using the locking mechanism, shared with the using the key. If one door jammed it could be a loose door or bent door hinge, but when both doors won't open the problem has to be sharing common interest (features). Removing panels from doors isnt going to be easy. Anyone with insight to "unique" problem solving, or experience will find this interesting, and your assistance would be ideal Thanks

The Actuator is not functioning anymore, check to see if there is a fuse for it first. If that is ok then remove the actuator and test it outside using some wire and your car battery to see if actually moves or doesent this will tell you if you need a replacement.

This could be a problem with your primary switch in the driver's door. Everything passes through that switch. Verify voltage continuity to the switch (Haynes or Chilton will give you a conclusive wiring schematic), and you must also verify that the switch itself is not faulty. Using a DMM (digital multi meter), measure the resistance (ohms) between 2 contact points, then hit the switch and verify that this number increases.

I have been dealing with the same problem and I'm a little further than you are. You need two people to do this job. Open the front door and it will give you access to the hinge pin. If I remember correctly you can pop off the snap rings and pull the pins. This will allow you to open the door just enough to get the interior panel off the door to allow you access to the actuator. Unfortunately, both my rear door actuators have been done twice in the last 5 weeks, But they are seized in the locked position again. I,m pretty sure its not just the actuators that are bad. Something else is causing this and that is why I'm here. Good luck with that one.
