For the high rpm part, have you looked to see if there is a vacuum leakage or possibly a fault in the Idle Air Control motor.

With overheating since jeeps are single belt driven it could be possible the fan is starting up when driving slow or parked because the belt is moving right. Or look for leaks in the coolant maybe it's not getting enough coolant.

fluid in the glove box though, can you be more specific with that one.

Engine will not idle, high idle ok. 1985 aries 2.2L


usually when a car wont iddle it may have a blown head gasket , remove oil filler cap on rocket or tappet cover check for creamy coloured oil , if so blown head gasket , also when morot is cool remove radiator cap and check fro brownish residue under cap if so blown head gasket .
remove each spark plug if one or more of them is white on tip of plug water is getting into cylinder ..

if none of these some carby's or throttle body's have iddle screww which can be adjusted to speed up iddle , or if throttle body it may have an iddle soleniod which may need to be replaced ,
i hope for you is is just and iddle issue , both the solenion and head gasket arnt cheap to fix.
the soliniod although easier to remove and replace its cost is usually .... expensive on most makes of cars , dont know why just because there greedy dealerships !

hope you need only to adjust carby or check timing is o.k

good luck hope this helps

If you put the thermostat in correctly (spring towards the engine) that should be OK. Likely if the water pump wasn't leaking or had a bad bearing, you wasted your $ on that.
If you re-filled it and did not have the heater on high heat, you may have some trapped air in there. But, still overheating says another thing. If you have a blown head gasket, it can pump compression into the cooling system and drive the coolant from the core. It will also overheat. You can have that tested at most any decent shop that will do a hydrocarbon test to find that.I think someone makes a chemical test kit for that but not sure if it's very expensive or not. White smoke from tailpipe will also be an indicator as will be any coolant in the engine oil or coolant on one or more spark plugs. If it turns out that it has a head gasket problem don't stop looking for problems as often a faulty fan or obstructed radiator can cause the initial overheat that caused the gasket to fail.

The fan works but my 2002 jeep grand cherokee wont blow heat what is wrong


It could be the thermostat or a plugged heater core. Check hoses going in to firewall after the vehicle has reached operating temperature for a drastic change in temperature if one hose is hot and the other cold or just warm your heater core could be plugged and would need to be flushed.
