Look for the water temp sensor on the right hand side of the engine as you stand in front of you car. It is situated above the gearbox bell housing if it is the same engine as the Corsa Lite 1.4. If you plug it out even if the engine is cold the fan must start running. if it does you know that the electrical circuit to the fan is fine but the sensor is faulty.

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.

My 2003 dodge durango keeps overheating , i just had new radiator put in and it started overheating again but now it is overheating with a very loud screeching noise like a belt sound what could be ca

as for noise will have to inspect under hood,could be fan or belt or pulley ,water pump .these are some things it could...My suggestion for overheating is replace thermostat. If your car has electric cooling fan then it may not be working..turn defrost on and if fan kicks on then fan motor is good..Now this does not mean that fan is working properly because fan is controlled by heat sensor switch that kicks fan on when motor reaches heat range......Things i would have checked....hope this information helps and good luck and Please rate my post...

Car was overheating replaced the thermostat now the heat isnt blowing hot and the car is over heating worse it's a mitsubishi galante

Could be that fan is not kicking on. check and make sure it is connected. could also be a vapor lock. some cars require bleeding water system and if so most bleeding screws are located around thermostat housing. Call local autozone and ask if your car requires bleeding water system....NOW the overheating could be from fan not kicking on and the best way to find out is to turn on defrost and if fan is working it will kick on automaticaly. If it does kick on then this shows that fan is working fine but this does not mean that fan is running properly.The fan is controlled by a heat sensor which kicks the fan on when motor reaches a curtain heat range. If this sensor is not working it will cause car to overheat.... Could be also that waterpump is bad.Not all waterpumps leak when they go bad.Sometimes the impeler on the waterpump which is what moves water through the system simply stops working and this would cuase it to overheat.......hope this info helps and good luck...Please rate my post and if you need more info fill free to contact me...Need to find where leak is coming from also for this is more than likely the problem........

My 92 Mazda 626 is over heating!!! Help me please, I've been tirelessly trying to find the reason and have found that my radiator fan is not kicking on at all..I tried to run power straight from the...

the first thing you have to do like you said try to wire the fan and see if it comes on and if it does, the fan is out of the question. next thing is can also be a stuck thermostat, the fan switch is activated once the thermostat is opened so if the thermostat is not opening it wont be activated, so get the car on normal operating temperature and once it starts going hotter then normal, feel the radiator hose on the bottom and top and notice the difference in temperature, if it is a big difference then the thermostat is not opening and you need to change it, let me know what you come up with, good luck

My car is running hot within 1 mile of me driving fan kicks on when it wants to....i need to know how to fix it myself

replace coolant temp, sensor and check for a bad fan relay. check relay first ! to test the fans, run a wire from positive on battery to positive on fan connection. then run a wire from negative battery post to neg, connection on fan. if the motors are ok. the fans will turn on. and make sure you have 12 volts going to fan motors. check relay first!! the fans on a typical engine only work when idling or going slow to prevent it from heating up. have a good day!! make sure there is no coolant leaks anywhere!! this will cause it to overheat also. if need be replace coolant pressure cap on overflow, might not be holding pressure.

Fan doesn't run while in idle and begins to over heat until I start driving agin then it cools back down to normal. Also the fan runs when engine is off and drains the battery.

The fan is only supposed to come on when there is excess heat .. in normal driving conditions it doesn't start. When you start your car in the morning the fan won't come on because the engine is cold.

With a hot engine - and it depends how hot the engine is - the fan will only kick in to prevent overheating. In heavy slow moving traffic or a traffic jam, the fan will kick in if needed.

The air flow through the radiator is usually sufficient -in normal driving conditions - to cool the engine.

When you park up and the car has a hot engine, the fan will kick in. This is perfectly normal. It is caused by a surge of hot coolant triggering the fan sensor. Perfectly normal.

The fan then should cut out after a while .. maybe 2-3 minutes at the most. If the fan runs continuously that suggests a fault in the temperature sensor switch.

Next time - wait by the car and see how long it takes for the fan to quit after you have parked up. It should stop of its own accord after a couple of minutes.

If the fan cuts off after a short while, and your battery is becoming drained, that's probably a battery or alternator fault.

Remember: when you start the car the fan won't kick in at idle speed because the engine is COLD, and there is no reason for the fan to start up ..
The fan WILL kick in for a couple of minutes after you have parked the vehicle and the engine is hot

Its not a solution but just a suggestion:
Check the heat sensor installed on the engine block (mostly linked with the water hose. you need to follow the wires from fan in backwards direction to find the heat sensor) and fuse (in fuse box) for the fan.
To check wheather the fan is working just disconnect it and connect the connectors directly with car battery.

2001 Mazda 626, intermittently overheats - especially but not always when not moving

Sounds like a fan issue...

Maybe a fuse, could be the relay.

Start the car and let it run at idle while not moving... if the car over heats and the fan never kicked on, then you need to figure out why it isn't kicking on.

to check the fan you simply need tro run a direct lead to the battery..if it doesn't come on then the motor is probably burnt up, if it comes on with a direct lead, then you have another issue.. fuse, relay, or thermostat.

Thermostat has been changed, radiator cooling fans wont kick on and the car still over heats. we checked the fuses and wiring and the fans run when direct connected to the battery. what next?

there is probly a fan sensor mounted on the block,and a lead that will go to the brain box or relay,if you have relay.check that also.hope this helps
