... Never had to replace ANY door or tail-door latches or mechanisms, or even adjust any of them in my '89 Pajero...
- Even the HVAC fan-switch was original, as was the indicator assembly. :wasntme:
- IMHO, 20 years is barely 'middle-aged'... (sez this 60's+ bloke...:p)
Seriously, When I last drove a nice LSE, the top glass popped open twice on a -sealed road - country run. Possibly assisted by the low-pressure area behind the car.
I suspect the body shell can move enough to allow an otherwise correct alignment to 'disengage'. - This (over-centre) modification keeps pressure on the glass top to stay 'down', therefore any momentary unlatching will not be taken advantage of, so to speak..
