Why do my radiator fans only work with AC?
Most likely the temperature sensor that operates the fan under normal circumstances is faulty. The AC controls may operate the fan from a place in the control circuit after the normal temp sensor so everything is OK when the AC is on. Also the Fan may be on continuously when the AC is operating.
Why is my Honda radiator fan not working?
If the radiator fan begins working, this is an indication that the fan relay is bad. If the fan switch relay is giving off the appropriate readings and is in working condition, move on to the next step. The thermo switch (also called the cooling fan switch) sends a signal to the cooling fan, so the fan turns on if the coolant gets too hot.
Why is my Honda AC / heat not working?
It retained its class-leading handling as it, along with the fourth and fifth generations, had front double wishbone suspension, the advanced independent suspension inspired by Honda’s racing research. The ac/heat worked great until a couple days ago. I noticed the fan was not blowing any air through the vents.
Can a radiator fan be turned on when the a / C is on?
Yes, the fan will come on when you turn the A/C on, so that proves the fan works. Leave the A/C off for the rest of the test. Start your vehicle, and let it idle for 10-15 minutes. Depending on the ambient temperature in your location, this should be long enough for the coolant temp to get hot and the thermostat to open up.
What does the thermo switch on a Honda radiator do?
If the fan switch relay is giving off the appropriate readings and is in working condition, move on to the next step. The thermo switch (also called the cooling fan switch) sends a signal to the cooling fan, so the fan turns on if the coolant gets too hot.
Why are the fans not working on my Honda?
I don’t think it’s the temp switch at the point where the radiator hose goes to the engine since the fans were getting power, which I assume means the switch is turning on. Also, I smelled the radiator fluid the next day, but then it went away and temp stayed normal. Thanks for any help! So the fans ARE getting power but are not running?
Why does the radiator fan not come on when the AC is on?
In order for the AC Condensor to do its job it must stay as cool as it can. As for the engine coolant temp sensor, if the coolant is not hot enough to make the fan come on, then there is no need for the fan yet and there is no problem.
Why is the radiator fan not working on my Honda Odyssey?
The Radiator Fan is not working during Normal Engine Run, but when i Turn-ON the AC, the Radiator Fan and Condenser Fan is working synchronously (Start and Stop at the same time). I could not locate the Radiator Fan switch?
Why is my Honda Civic running so hot?
A Civic’s engine lies alongside the A/C setup under the hood, so if you can’t find anything wrong with the freon levels or the compressor, you may need to consider a different source. If you discover that the engine is running hot, its proximity to the A/C will negatively affect the system’s cooling capacity.
