I got to start tracing a short in my door locks. I thought it was the switches but it is not.
Front doors work fine but the 3 rear doors short out on unlock position and won't unlock all the way. And this happens randomly.
My guess would be that you have broken wiring inside one or more of the rubber boots that span between the door and the body. Very common failure in some of the German stuff I used to work on. Not sure if it's common to Squares, but it'd be the first place I'd look if it was mine. The rear probably doesn't function well because the old lithium grease is all dry and turned to sticky clay. Remove that right door inner panel, clean all the lock mechanism components with WD-40 (crappy lubricant, but a great solvent cleaner), relube with Triflow and see how it functions before you put the door panel back on.
