Radiator Fan Doesnt Turn On

When you turn the ac on 12 vdc from the lock controller turns on the condensor fan motor relay lo it also turns on the radiator fan motor control relay.

1057 the fan jeremy conn. I have to turn on the ac off when at a red light or in heavy traffic and turn it back on when im moving again i think it was something called the ect sensor if im remembering correctly. Looking the relayfuse box i am not sure which one is for radiator fan. With the ac off if the ac condenser fan needs to turn on to cool the engine then why not the main radiator cooling fan 4 is the fan replacement warranted at this point.

Hey guys so my radiator fan isnt turning on. Could my radiator fan be perfectly ok. Now running tests with the car in park and i cant get it to go past the normal temp about 1980f for my 08 hhr.

When a radiator fan works it usually makes a whirring sound that is easily noticeable. You turn on your ac and you should get the signal to turn on the radiator fan. So my guess is it might be the relay.

You can check signal by running the car in park and check if you get a signal from the ecu at the fuse box. When the ac is of the radiator hoses both become same heat after a while and the overflow reservoir starts boiling over and the fan do not kick in. My cooling fan wont turn on when i turn the ac on.

This one doesnt make sense. Ground from the radiator fan motor control relay turning on is applied to the radiator fan motor relay lo which turns the radiator fan on in the low speed mode. Do you have a dodge caravan chrysler town and country or plymouth voyager van and are experiencing an overheating condition while in traffic or at stops but.

If the relay doesnt fix it then you have a signal issue. And when i do turn my ac on the car seems to get hotterit had reached 2300f at one point but i got no lights saying it overheated and i never let it go higher to see. The ecu signals the radiator fan to work at the precise time.

Could anyone please help me in. I have jumpered the ect switch using a paper clip and turn the ignition on and the fan didnt start. When i turn on the ac the fan works and keeps the car cool.

Visually check the fan if you dont hear its noise. My 2013 hyundai i10 has one fan and as far as i can see one coolant temp sensor. 3 ive read that the radiator fan wont kick in until 213 degrees.

Or should i check the sensor first. The fans arent coming on when theyre supposed to. I replaced water pump and radiator and coolant temp sensor.

If you dont get a signal then theres likely something wrong with the wiring or ecu side of.
