Just kneel down in front of your XJ.
Look between the bumper and the grille.https://www.rockauto.com/en/catalog/jeep,2011,grand+cherokee,3.6l+v6,1446514,heat+&+air+conditioning,ambient+air+temperature+sensor,7000

Since you are doing a rebuild, There is a tool made just for changing the cam bearings. If you are going into it that far, it is VERY worthwhile to have the block boiled and then replace the welsh plugs (freeze plugs) as well as the cam bearings. Jeep blocks tend to rust up inside the water jackets and accumulate crud in the oil passages.
As long as you are doing that, do it right!! Most machine shops charge very little to replace the cam bearings especially if they do the boil out for you. Unless you can rent or get the bearing tool cheaply, it's worth having that done.

you may have to get the system vacuum pumped and recharged

I suggest check the Jeep XJ Cherokee Repair Manual (Section 24-Heating-and-Air-Conditioning).

Hope this helped (remember rated this) Good luck.

here can find two documents:
- Jeep XJ Cooling-System Section 7
- Jeep XJ Cooling-System Section 7a

Also, the other sections about Jeep XJ Cherokee Service Manual

Hope thats help (remember rated this). Good luck.

possible fuel pump

sounds like the clutch field on or bearing on the front of the compressor went bad take a closer look at the pulley on the comp. and see if there is any debris or melted plastic coming out behind the pulley,if so the clutch,field and bearing should be replaced,hope this helps

You need to get a manual for the correct procedure of taking the dashboard out.
