96 sebring fan not running when hot or runs constantly

check temperature sensor?

Your A/C has it's own little radiator that sits right in front of your engine's water-filled radiator. Heat from your engine radiator is prolly transferring itself into the other smaller radiator and over-whelming it. When any engine is running hot, it usually turns out to be a bad themostat, bad temp-sensors (that run your electric cooling fans on the radiator (or one (or both) radiator fans have died). I would start with the thermostat since it's the cheapest....

Hello, Have you checked the coolant level in the vehicle? Also when the car is running hot do you notice if the cooling fan is coming on or not? Could also be a sticky thermostat not allowing cooling to enter the engine from the radiator. PLEASE NOTE THAT THE CAR MUST BE COOL BEFORE OPENING THE RESERVOIR AS IT IS A PRESSURIZED SYSTEM. Hope that helps.

SOUND LIKE YOU HAVE A FAULTY FAN CONTROL RELAY.

Hi! First of all the temp gauge is faulty so you will need to replace the temperature sending unit. The cut off may be caused by a faulty spark plug. Please have a sparkplug replacement as a first course of action. Hope this helps and have a good one!

did you check the relay?

check to see if the cooling fans are turning on

Check under the hood and see if you have a decal that says fan may turn on after car is turned off. The fan can run for 10-15min after shut-off.
If it's on for only that length of time and it's killing your battery, you may need a new battery.
If it's not turning off at all, open fuse compartment under the hood, take a small rubber mallet and start to tap the relays. There should be one there for the cooling fan. Once you find it, (the fan will turn off when it's tapped) you can exchange the relay for another (of the same part number - like the wiper relay or A/C relay or something) restart car, let it run til hot, and turn off. If fan shuts off within 10-15 minutes, you need a new relay.

check the heater coil and hoses

We just had a similar problem with my daughter's car. We replace the Idle Air Control Sensor ($225 including diagnostic and labor). It is running great now. Hope this helps.
