Odd question

Scenario:
Car's fan is not turning on but the temperature indicator is not skyrocketing to hot. The dial indicator stays at normal temperature about half way.

Is this possible? Or will the climate indicator always shoot up to hot letting me know its over heating?

 

Does the fan run if you unplug the fan switch on the thermostat housing and then jump the 2P connector?

 

Yes everything works but a friend of mines wants to know because he thinks his fan isn't turning on quick enough so he thinks it might start over heating.. He thinks there might be something wrong with his climate indicator or something. But we just want to make sure that the climate gauge will always shoot up to hot if it ever overheats so that he can immediately pull over and shut off his engine before any damage occurs.

 

if the car isn't overheating then don't worry about it. im sure if you let the car idle long enough the fan will eventually kick on. oem fan doesn come on until about 200* anyways.

if there is a problem with the temp gauge you will know. it will generally not register at all or peg straight to hot with the key on if there is a problem.

 

Okay thanks! Im asking because we started the car and let it idle for a long time. The temperature gauge is at half way but the fan still isn't kicking in until we start driving it like 20 mins later or something.. weird

 

Hey how would you jump an unplugged fan switch if the fan switch only has 1 pin? I know that hondas have 2 pins which you can just jump back together with a hair clip and turn on the car so that the fan spins. But what if the fan switch only has 1 pin? How would you go on jumping that? Btw we are also working on a toyota corolla which only has 1 pin for its fan switch

 

Do you have a circuit diagram? If so, post it.

 

I don't but I can take pictures of the 1 pin sensor and post them up. Just wanted to know if you know how to jump a 1 pin connector.

Wait.. I actually downloaded plenty but I dont know which one to put up. Let me check

 

If I can see the radiator fan circuit diagram, I can tell you what to do. Otherwise, I'd be guessing, which I prefer not to do.

 

Here you go I hope this is the right one you need

 

Can you read it? I have it in pdf format if you prefer that instead

 

That's for the heater blower motor in the cabin. Post the one for the radiator fan.

 

K hold up let me convert it. I think its gonna be hard to read though

 

Couldn't find radiator but it does say Cooling System so I hope this helps

 

Ground the single Lt Grn wire in the radiator fan switch plug on exposed metal of the radiator support where the fan switch is located. With the key in ON(II), the radiator fan should run.

 

Dam your smart. Thanks alot! I have to try this tomorrow though but you are right about the light green wire. Its weird how Toyota only has 1 wire for the fan sensor

 

The switch grounds locally on the radiator support rather than having a separate ground wire. Kind of like the Civic starter. Good luck.
