So I have an '89 GW and have been trying to get the rear tailgate to unlatch. I have been able to get the rear window down, but when I try unlatching handle to open, tailgate won't budge. With window up and access panel open, I can see latch mechanisms trying to unlatch, but won't release tailgate. I've sprayed with lubricant/PG Blaster, but still cannot get them to release in order to drop tailgate so I can work on window repairs.
Any ideas, outside of trying to reach hinge bolts to unbolt tailgate?
