I just got a 1997 Jeep Grand Cherokee Laredo. Pretty nice, but before I bought it, the latch for the rear glass hatch wasn't working(wouldn't open the glass hatch). Well, they agreed to fix it and they did, but the latch doesn't lock at all when you lock up the car, so you could actually break into it, by merely opening the latch, and crawling in the back. If anybody knows what the problem is, and how to fix this, I'd appreciate it(obvioulsy I don't want to leave it like that). Thanx.
