My radiator fan is NOT coming on in my Eg/GSR Hybrid. First time driving her today Biatch hauls a$$

Anyhow, I changed the relay in the fuse box and checked to make sure the fan is not broke.

I would like to go ahead and wire the fan in to come on when the car is ON and turn off when the car is off. I know if I go staright to the battery that the fan would not turn off until the battery dies, so how / where do I tap in for an accessory? I guess I am looking for something close and not one of the radio wires inside the car

Any tips on this would be very helpful! Thanks!

PS <> Pop's is saying that it may be bad for the motor in the winter if the fan is running ALL the time. I was thinking wiring into an accesory power wire and adding a toggle switch under the dash. This way I could control the fan with a switch but still not have to worry about it running when I left the car. Thanks for any advice!

 

Run a wire (the positive one of course) from the fan harness to a toggle switch that you install in the cabin, that way you can turn it on and off when you want. Just make sure you run the other wire from the toggle switch to a source wire that goes dead when you turn the ignition to "off". Otherwise if you forget to turn the fan off you run the risk of draining your battery.

Also, to test for an "accesory wire" use a multimeter! Very useful for this kind of job!

P.S. I did it and it works well for me!

Ok thanks for the info! I am getting on this in the morning. I have a Craftsman multimeter but have no idea what setting to put it on to check for an accessory wire. All I know how to do with the multimeter is to find the two ends of a single wire. Came in handy to find wires on the shock tower from various sensors

I appreciate the help. Is there an accessory wire close by the fan or do I have to go back to the fuse box?

Later!

This is VERY similar to the meter we have here at the house. Ours just doesn't have the yellow "temp" thing below the dial or the other two hole thingy on the right. But, the dial looks identical.

 

Well, make sure to set the multimeter to a voltage setting over 12V. Then you need to test the wire by using the red lead on the wire itself and the black lead touching to a chassis ground. If you do it right you should get a voltage to display with the ignition turned "on" and then when the ignition is "off" it should have zero voltage.

So, I touch the red pointer to a power wire with the ignition on and then off to check for "0". ...When I ground, I just put the black pointer on the chasis. I'll ground the one wire from the fan close to the fan. Just want to make sure I am right before I start touching $hit. Why does it have to be set higher than 12v and not at 12v? Just curious. Thanks anyhow for the help!

 

have you checked to see if the thermoswitch harness has been hooked up? you can change out the thermostat and thermoswitch while you're at it to see if that eliminates your problems of overheating and the fan not turning on.

 

yea, i would check to see if your thermostat is opening. also check the resistance of your fan switch to see if its good. that way you don't have to wire it up so its always on.

 

You can wire it to the lighter. I did that and added a switch. I believe the positive wire is white/black, but my Helms says it's yellow/red. I distinctly remember white/black. Ground is solid black. I just grounded the fan to the chasis like you mentioned above. Here's how you get behind the lighter area (if you want to use a switch, which I recommend):

 

I'm going to just wire the fan into a switch. Before I yanked the Cx motor I had the same problem with the motor over heating. I changed the thermostat and it did not help. I bet the entire time the fan has not been turning on which is giving this newer motor the same problem.

 

try replacing the thermoswitch for a lower temperature one before you do a direct wire.

Where exactly is the thermoswitch? I tested the harness that plugs into the fan and it's not getting any power.

 

the thermoswitch is on the outside of the thermostat housing. just follow the lower radiator house to the side of the head and you'll see the housing and a gray (?) female plug, plugged up to a green or blue male plug. don't remember the exact color but here is a visual aid:

MUGEN thurmoswitch?
that thing must cost an arm and a leg

 

I have found on mine, If you just ground the fan control wire that goes to the ecu, the fan will turn on whenever the car is in the on position. Quick and simple and no need to clutter the engine bay with new wires.

 

I think you just need to have a switch and turn it on whenever your car starts to overheat.

This is what I did to mine. I can turn the fan on whenever. When I go to a friends house for a second I leave it on and then when I leave I just turn it off (max. 5 min. period). It is really easy. All you have to do is find the plug for the fan and splice it with a butt connector and then run the wires and your set. Took me and my friend longer to hide the wires then it did to run them. In my opinion it is one of the best 5$ mods you can do.

Someone said the vtec won't work properly if the engine is not at the right temp. (too cool)????
