One day out of blue 3 of my 4 doors on my car listed above wouldn’t open from inside and passenger rear won’t open from the inside or out. Locks all work when I hit switch, but doors won’t open from inside. The driver's door works great. They all stopped on the same day. Fuses etc, good. Never had anything like this where 3 out of 4 won’t open from inside and one won’t open from inside or out quit at the same time. Any ideas or help would be great!

The first item to check would be if someone tripped the child safety locks or if they may have started to fail and are causing the doors to not open from the inside. They work in an interesting way, there is a tab on the door latch that allows the rods from the handle to operate the latch. If the tab is moved by either the child lock or it falls off from rust, the interior handle will no longer open the door. If that isn't the issue, then you will likely need to get to the latch and see if that piece had failed.
