New to jeep.

It is my neighbor's jeep it is a 2004 liberty I think. The traction light is on and the glass in the back won't latch. I have given it a shot of dry graphite and it didn't help. Is there any adjustments for the latch.

Take a look at the hinges… IIRC they are adjustable for that purpose. One side may have slipped putting it out of alignment.

Sometimes the latch doesn't release when manually opened. There's a little electric switch behind the handle that releases the glass. Try using the key fob to open the glass latch which may allow you to then close it.

Traction control light is probably an ABS sensor or wiring fault, a good code reader will narrow it down.

I looked briefly at the rear hatchback it will release fine but it won't grab to shut. The only tester I have is a harbor freight special and they don't have a lot of money.

Try unplugging the tailgate handle, there is a microswitch in there that unlatches the glass, it is known to fail and make the glass pop open randomly. If that doesn't work then you probably need to get another latch from a scrapper.
Check the ABS sensor wiring, I'm guessing it's later than 04 if it's got traction control, it will have a sensor at each wheel. If there is no obvious wiring fault then a garage with a scanner shouldn't change much to tell you which one is in fault, cheaper than replacing sensors until you find it.
