That 1988 GMC
Newbie
My OBS is a 1988 GMC K2500 with manual door locks and manual windows. Out of nowhere my driver side door wouldn't open from the outside, and 2 door openings later using the inside handle, that doesn't work anymore. No evidence that anyone tried to break into the truck. Passenger side door opens fine inside and out.. Any tips on getting the driver side door open again so I can do further diagnosis of what the issue is will be greatly appreciated. Also thanks in advance.
