2000 Jeep Grand Cherokee limited 4X4

I purchased a Grand Cherokee 4 months ago and now the horn works sometimes and doesn’t work at other times. Help

And my hatch doesn’t lock. (as of a week ago) Help.

it is better to have a hatch that doesnt lock than one that wont unlock I guess. You can get a new latch mechanism and it should not be too hard to change.
Horns are notorious for not working, kind of like car clocks. Could be the contact on the ring in the steering collum, or it could be the horn itself has a bad noise maker. Both small problems as problems go, but any good mechanic can trouble shoot these two, and fix em both in a few hours.
