Outside temp shows normal at vehicle start up. If left idle when at operating temp outside air temp shows 113 F. Jeep is not running hot and both fans are working
I may be wrong but that sensor is for the ac not for engine operation and at 113 if its not that hot then the sensor is bad but if its summer its ok,, your engine works with intake air temp
SOURCE: Heater blows cold air
If the "Heater In Hose" gets hot, and the "Heater Out Hose" does not get hot, than either the Control Valve is sticking closed, or your heater core is plugged up with ****!
Have you used "Barrs Leak" or a simular product for a radiator leak? That will sometimes clog the heater core.
I have a 1993 Grand Cherokee, which "Normally" throws very hot air out of the heater, but lately sometimes it only throws warm air, till I make my first stop, than it gets hot.....all because the heat control valve is hanging up.
Low water in the radiator will also cause a heater to not work.....if the water level is too low to circulate to the heater.

If jeep is a limited model it has automatic temp control for the heater blend door, it is controled by a electric motor, and can be problematic with age,sometimes it makes a clicking noise when the blend door is stiff ,which then it must be lubed and freed up
SOURCE: clutch won't engage on air conditioning compressor
The air gap may be too wide between the clutch disc and plate. It usually happens from wear. You can test this possibility by engaging the clutch electrically as you have done and then push on the disc slightly with the handle of a hammer or screwdriver. Be careful not to get your hand or fingers too close while the engine is running. Basically you are helping the magnetic field pull the disc in. I hope this helps.

Sounds like you have done all but 2 things to treat this. Double check the wiring to any loose connections or breaks. If good replace the electric fan itself. Because of the nature of electric fans most are not engaged when the vehicle is moving but should kick in when it is sitting engine on even if the AC is not running. The AC control actually provides extra voltage to the fan to run at a higher speed. It sounds like you have lost one of the speeds to your fan.
