Generally, if your car has electric fan or fans, look for a temperature control possibly being bad. You first need to check to see if power is getting to the fans. Also, besure they have a good ground. If there is full power to the fan(s),(12v), then the fans are bad. Replace them. If no power, look farther up the circuit. Be sure the temperature sensor is working. You need a meter or 12v trouble light to test these items. If you need, I can tell you how to make one. It's too easy. Good Luck

couple of reasons
have a compression test done to determine head gasket or cracked head
watch closely when the over heating starts and if it cools down
it the temp rises when going slow ( heavy traffic, hard pulling up hills , stop lights -- basically when the road speed is low and there is low/no air through the radiator-- check for a faulty fan clutch or viscous fan hub failure ( spins but doesn't pull air )
check for thermostat failure and not opening if from a cold start it is going to over heat within 5 miles of 10 minutes of idling
check for blocked radiator(internal)cores or radiator fins (external) falling off the cores
The first point of call for me would be the fan drive system

2010 Lincoln MKS Heated Seat on driver's side stopped working (Light in button turns off on its' own)

The most common cause of this problem is that the drivers seat heater grid is open or burned out. That is based on 25 years as a Ford dealer technician.

Hi guys I am new on this, I will start all over, I got this big problem for me, I got this 2002 huyndai elantra gt, 1 week ago I was driving and the heat stopped working, no radiator leak, everything...

Ok, here is my take on your problem. As you may already know, it takes a car a few min. to actually warm up to operating temp. When the coolent reaches operating temp. the thermostat opens to circulate the coolent in the radiator. Now, as your drive, the air pushing against your car will actually blow some air through your heating system ducts and into the passenger compartment. Is it possible that your blower fan isn't working? Because while you are stopped, there would be no air forcing its way through your ducts, thus no heat. As your drive, your car gets up to operating temp, heats up, and the air pressure as your drive will blow some heat out into the passenger compartment? On a side note, if your thermostat is stuck in the open position, it would take it forever to warm up since it is circulating ALL the coolent even tho it isn't at operating temp. A thermostat stuck open will take 30 min or more before you actually feel any warmth, if at all in the winter.. your thermostat opens and closes constantly as the engine is running to keep it at its normal temp, usually around 160-180 degrees. If you live where it gets really cold, a thermostat stuck open likely will never get warm. If your blower motor works, and your engine don't overheat, im 98% sure its your thermostat.

have a compression test done to check for head gasket or cracks.. Check coolant level in the radiator not the reservoir. Have a cooling system pressure test done to check for leaks. Have a flow test done on the radiator to check for blocked cores. Have the fault codes read to check for sensor/ servo failure.

Why does the temp gadge go up when the car is sitting still????

If the temp goes up at idle and is fine when your driving at highway speeds than the most likley problem is the cooling fans are not working.

the first thing you can do is check to make sure both of the cooling fan fuses are good. you can also check continuity of the cooling fans with an ohm meter.

The cooling fans are turned on by the low and high speed cooling fan relays. you can try swapping the relays.

If the fans still do not come on than you will need a scan tool to diagnose further since the PCM is what controls the fan relays.
