Not me! But I digress. It seems that the cold start heater is stuck or broken...check it out.

SOURCE: 2001 jeep grand cherokee overheating

is the radiator fan coming on and staying on, or not coming on at all?? i was having the same problem, and it turned out to be a fan relay switch which was pretty easy to replace. around 40 bucks, and maybe 30-45 mins.

SOURCE: Very rough idle on 2002 Jeep Grand Cherokee Limited Edition V8

If you haven't changed the plugs or had the fuel system cleaned, now would be a good time to do it. The number 1 culprit for rough idles is dirty injectors or plugs. You can try an injector cleaner in a can (or bottle) for under $10 and see if it helps, and then work from there. If there isn't any improvement then if you are able to, check the plugs for any gunky buildup and if you find a bad plug, make sure you replace them all (or have them replaced) at the same time.

SOURCE: 1995 Jeep Grand Cherokee squeaking and power steering

The squeaking is definately from the belts.
Have you tried adjusting them ?
Since now the power steering has failed it could be due to the power steering pump bearings,may be tight to rotate and thus the squeaking noise, or you may just need to replace the belts.
WD-40 wouldnt work permanently..try using STP belt dresser.
Hope this helps!

Disconnecting your battery, as you must've done when changing the starter, will cause the ecu to revert to factory settings and the computer will have to relearn the proper idle for your jeep.

Sounds like a loose belt, Depending on what engine etc., it may need to be changed or if you have adjustment, tightened. When adjustment or replacement done, is a good time to check all pulleys. If your not up to it, an adjustment should not cost too much, few minutes work in most cases, if belt needs changing, price of belt & a little more labor involved.
