1996 Cherokee sport 4.0 replaced thermostat temperature gauge not reading. Cool air blowing no heat could this be a bad temperature sensor If so where is it located. Any ideas?

If you are blowing cold air, it probably not a temperature sensor problem. Was the thermostat put in right - side - up??? Also, the sensor wire could have possibly broken or come unplugged while you were installing the new thermostat. And there are only a couple of reasons your only getting cold air now and that is (a) you installed the thermostat wrong or(b) the new one is defective. Remember to replace the coolant. Sounds simple but too many forget too.
It could also be that the small plunger, just to to the left of the spark plugs/toward the back of the engine, is just stuck. Had this happen many years ago. Pull on it and then spray it with lubricant.

Would a thermostat set for a higher temperature keep the heater from blowing hot air?
No. The thermostat controls the flow of water through the radiator, not the heating core. Using a thermostat with a higher temperature rating delay the opening of the thermostat (and the flow of water to the radiator) until that higher temperature is reached. This will cause the coolant to run hotter.
Why is your dodge Dakota blowing out luke warm air out of the heater when it's cold outside?
thermostat probably stuck open needs to be checked or replaced
When I drive car the temperature gage goes down to cool and only Luke warm air is blowing?
try replacing the thermostat

heater core plugged or air locked check to see if hoses going to heater core are hot
Can the thermostat be bad if the heater doesn't work?
If you are not getting heated air blowing from the heater core and your engine coolant temperature gauge is showing LOW or below normal , ( then YES , IT'S POSSIBLE that your engine cooling thermostat is sticking open )
Why is a 1994 Chrysler Concorde not blowing hot air from the heater?
Low coolant? Thermostat not closing completely allowing engine temperature to rise? Plugged heater core? Temperature blend door malfunction in the HVAC housing.
I Replaced heater core and had ac rechaged now Heater not blowing hot and ac not blowing cold air Why?
The heater core is usually your last resort. So now start from the end to the beginning, core, thermostat, flush, hose, fluids. Follow the trail and your bound to find your answer.
Just had intake gasket fixed then turned around and had to get the heater core fixed now it is not blowing out hot air out of the heater why?
Check the temperature gauge. If it is running cold, replace the thermostat.
Can an automobile thermostat stick open?
Yes they can stick open or closed. An automobile thermostat is just as likely to stick open as it is to stick shut. Symptoms of a stuck open thermostat are slow to reach normal operating temperature and only warm air blowing from the heater. Symptoms of a stuck closed thermostat are engine over-heating and radiator boil-over.
