what is the temperature co efficient of resistance of a thermister
Electronic Thermister
Thermostat is a mechanical device that reacts to heat. As heat is applied the thermostat contracts and allows water to flow through the system. A thermistor is a thermal resistance sensor that also reacts to heat. There are two kinds, one is a negative coefficient and is a positive coefficient. As heat increases it changes the resistance value of the thermistor. That resistance value is transmitted to the computer and/or temperature gauge. Through computation the computer can can tell what temperature the engine is at to make decisions on how it should be run.

what is the temperature co efficient of resistance of a thermister
A thermister is a resistor that depends on tempature, the higher the temp the lower the resistance t, the lower the temp the higher the resistance
A thermometer or thermister

If the system has a full charge then the thermister is most likely the cause for it not working.
ARE YOUR FANS COMING ON? If they aren't coming on, it could be the thermister in the thermostat housing, a blown relay, bad fan motors or wiring OR the thermistor (not the thermostat).
A Thermistor Is essentially a variable resistor. The resistance of the thermistor changes with temperature. They're often used to regulate heating elements - like those found in cookers.
The lock actuator contains a thermistor wired in series with a small DC motor. The thermistor will quickly heat up when the lock switch is pressed. This causes the resistance to also increase qucikly there by reducing the current flow to the motor. This is a protective function that prevents damage to the lock actuator if the switch is held down too long. It should function several times before the thermister begins to limit the current but over time these devices will weaken and limit the current too quickly. Some time to the point where the doors will not lock or unlock anymore. This requires the lock actuators be replaced. The old thermistor can be removed and a new installed but this takes some effort to find the correct current value thermister.
A thermister is a device that changes resistance depending on temperature. A photo resistor changes resistance based on light. Both of these could be used with an amplifying circuit to vary current flow.
It stands for Non Electro Static Formulation A. They use a layer of stannic oxide, a thermister, and a layer of vinyl. The window is electrically heated to prevent ice formation and also prevents shattering in the case of a bird strike.
It could be freon, it could be various other things.. Have your freon checked first there may be a faulty thermister behind your glove box . it regulates the temperature of the a/c...be sure your freon is up to specs before you begin troubleshooting the system
