Door latch stuck on volvo c70
It sounds like the actuators (usually stiff wires) from the door handles and locking knob are OK, which means the latching mechanism itself is probably jammed or broken.
You'll need to remove the upholstered panel covering the inside of the door (search online for "how to remove a door panel") and investigate, pulling on various rods or cables to get the latch to release. You may have to temporarily remove part of a plastic water shield under the door panel to gain access.
If you can get the latch to release, unbolt it from the door (usually from its side), spray every part of the mechanism that you can access with a light lubricant like WD-40, and see if that helps. Try operating the latch manually by pushing with a screwdriver to see what happens. Look for any broken or jammed components or connectors.
If it still doesn't work, but all the related handles and knobs appear to be connected and moving properly, then the latching mechanism itself is probably at fault. Removing it is usually a matter of disconnecting all the control wires or cables, but take notes on how they connect so you can re-assemble everything). New latches are available from the manufacturer, or you can probably find a used one online. These are normally very reliable items, so I wouldn't hesitate to buy a used one.
