There is no timming tool, timming is set and maintained by the engine controller. there is also a map sensor on the front of manifold.

please elaborate, does your inside fan still works? does your compressor clutch kicks in?...would you know if you have refrigerant in your system? if you can trace the hose from the compressor to the evaporator, you can see a plastic cap normally blue with a big letter "L" at the top, then it is the low side fitting, you can remove the cap and get a pin and press the pin at the center( be carefull, refrigerant might be present). if there is none, then you have a leak. u lost all of your refrigerant that is why the ac did not work. if you do have a big burst of gas as you press it, then it is not a refrigerant problem,
a lot more to be tackle as you help me diagnose your problem.
tnx

SOURCE: Liberty Jeep 2002 at what milage do I change the timing belt?
First does it have a belt ore a chain and most newer one recomend at like 60k ore 90. If got a chain it stretch and you will not get great gas milage but it will not break like a belt
