When the temp is below 60, the lift gate open light, bell and lights come on. they dont stay on, but go off and on often. the bell will literally go ding, ding ding repeatedly. jeep doesnt know how to fix it and neither do 2 other mechanics. i have spent almost $500 on this and its driving me nuts! help!
Sounds like the cold temps cause the metal door to warp which causes an increased distance to the sensor that tells the computer the lift gate is open. The lift gate sensors should be adjusted to be closer together.

It probably will cost a few bucks to get the code reset, but you don't need to go to the dealership, most shops with a good scanner equipped for air bag code reading will be able to diagnose and reset the light. The most probable reason for the code is the battery being dead for a while, there is a capacitor in the airbag circuit to make sure the airbag can go off in a collision even if the battery disconnects itself in the process. There is a slim chance it might be something else but either way the shop should be able to tell you what the problem is, and get it fixed... But, just for fun, before doing all this, i'd disconnect the battery for 30 minutes to an hour and reconnect it back, some systems do effectively reset themselves this way.

I've had the ABS problem several times, and each time it was a failing wheel speed sensor.

I had this same problem on a taurus and did all the things you did and found out after that the coolant reserviour bottle had a crack in the bottom of it

OK, this minor collision may have shifted the actual clip and latch assembly. You may have to totally disassemble the latch assembly to release this lift gate.
Any kind of major or minor shifting of the lift gate lock latch assembly can cause misalignment that will jam this delicate precise locking mechanism.
