In the early 140s the trunk handle was driven off the pump under the rear seat, black hose going to port SFG. There was a service bulletin in 95 to relocate it to the close asssist pump, where it is in line with the retracting stiker (which required a new latch). A quick test would be to rotate the lower latch and see if the upper latch draws in if it does not the trouble lies in either the pump, the lines going to the latch, the latch or the handle. The next step would be to pull the fuse in location 9 in the trunk to see if this brings this back to life. The other thing to check is the screws on the lower latch loosening allowing the latch to move upward.
