Why does my radiator fan not work at high speed?
Why does my radiator fan not work at high speed?
Check the electric radiator fan, if vehicle heats up at low speed then it sounds like the fan is not working! at high speed the air going through the radiator cools the engine. Check the fan out! God-Bless! Hope this helps you. or check to see if you have a bad fuse for the fan or relay is bad and will not turn on fan.
When do you turn on the radiator fan?
This fan should only run when the a/c is on or when the engine temperature has reached about 218 degrees. Once the a/c is off or the engine temp drops to about 210 degrees it shuts back off again. It rarely comes on at speeds over about 35 mph because at that speed enough air is forced through the radiator to keep the engine at about 198 degrees.
What are the symptoms of a bad cooling fan?
Common signs include the engine overheating, cooling fan only working at certain speeds, and the fan never turning off.
What happens when a cooling fan resistor fails?
The cooling fan resistor is meant to send power to the fans in steps, so that the fans may operate at different speeds. If any of the individual steps or switches fail, it will disable the cooling fans from operating on that speed setting. You may notice that the cooling fans only operate at one speed, when they used to operate on two or more. 3.

Which is the highest speed of the radiator fan?
But anyway, my radiator fan seems to only operate at the highest speed. 10-20 seconds jet engine mode –> off –> repeat when it’s hot outside.
How does a high speed fan control relay work?
When the engine temperature reaches 200 degree’s the PCM energizes 1 to 3 Cooling fan relay’s in the battery junction box (fuse-relays ) The low speed fan relay , High speed fan control relay 1 , an high speed fan control relay 2 . Now what problem are you having ?
