1987 jeep cherokee driver door won't open
you could try this....wild as it sounds~ http://www.youtube.com/watch?v=6YK7wpw_pXg
1987 should have some slop in the window tracks try rolling the window down and get a high intensity light with a pinpoint beam and you might be able to see the linkage to the latch assembly, some times you can use a metal coat hanger with a hook bent on the end and slide down to the latch and give it just that extra pull to release the latch and or lock pawl, things are most likely just worn enough to cause this.
