I have a 99 outback wagon with trunk latch stuck. It's not the little spring having come off, it's not rust on the linkage, it's not electrical, both the external link arms are free and move normally. I've had all those things happen multiple times over the years, and I have always been able to get it open. I am familiar with all the parts that are there and how they work. I now have the interior access panel removed. This is a high mile car with very heavy hatch useage.Every piece of the latch and linkage is clean, lightly lubricated, just very normal in appearance. You cannot move the external lever. I unhooked it and it the lever now moves free. I can move the lock lever on the latch and see the external parts move OK. At some point deep in the mechanism, The latch is jammed, There is a little tab which actuates that internal linkage. I can put pretty hard pressure on it with a screwdriver tip, but it does not disengage. I have unbolted the three bolts that hold the latch assembly to the hatch, but the latch is solidly stuck to the bar below holding the latch shut. I thought I might be able to move it side to side or get a bit of a twist, but no help. I have gotten to the point where I had a very large pry bar under it while trying to pressure the linkage tab with a screwdriver. This also did nothing.
I think it's going to be drilled or cut out as a last resort. Has anybody actually had to do this, and what worked?
