On my 1991 GMC Suburban, 207,000 miles equipped with power locks, the rear barn doors do not open. I have noticed that the thumb button seems to pop in and out without engaging the internal mechanisms. I have looked inside the access panel and explored the linkages and whatnot, but I am lost. I prefer to do repairs myself, but this is really challenging. please help!
