I tried feeling around inside the door area after taking off.
Chevy truck door latch stuck.
You may also want to check with a mechanic to ensure it isn t a warning that the mechanism may need repair or replacement.
The door is not completely shut and will not open.
You can take a long screw driver of piece of drill rod and manipulate the lever that opens the latch to get the door open and make repairs as needed.
After 40 50 or 60 years of service the doors on your chevy or gmc truck have opened and closed thousands of times.
Which means your door latches could be worn out leading to rattles and doors that don t open and close properly.
Took off inside panel and seat belt assembly then unscrewed latch assembly again sprayed the rusted latch and worked it until it was free not easy but with patience.
Roll the window down and carefully push the door panel away at the top right above the latch rear of door then look down inside the door at the latch and figure out which rod fell of the latch.
The electric part will move the door latch rod that sticks up by the window works up down and by using the interior door handle it still won t release the latch.
The door will not close all the way nor will it release the latch.
It is also possible that the door latch is rusted or stuck so cleaning the door latch with wd 40 might help.
We have new door latch assemblies for all 1947 72 chevrolet and gmc trucks to make sure yours close rattle free.
Waited tried door waited tried door repeat for over an hour got rough with door by holding handle open and pulled until it started to move then worked it until it opened.
I may be a few years behind in answering about your truck door locking i have a 2010 chev silverado extended cab 4x4 and it does the same thing on the driver s door kind of scary cause i can t get out of my truck from that side i played a bit with the manual door lock button the key outside and the power door lock it started to work after that but sometimes it acts up again i don t know if it.
