Yeah i was wondering how i would be able to toggle my radiator fan on/off with a switch in my car. What wires would i have to splice into and such would help. I dont want to bypass the heat sensor cause i want it to toggle on when it gets to hot. Basically what i want to do is toggle the fan on/off when the car is off. It's a 94 EG hatchback with a mini-me

Thanks

 

hrmmm.. i remember doing this with my maxima. find the hot/cold wires that go to the fans harness, cut the red wire, wire it to a switch and viola.. easy enough.

 

i just noticed you said you didnt want to bypass the heat sensor. so i dont know, i guess if you cut the wire past the heat sensor it might work, or wire it up to a relay? *shrug* but thats the way to do it without the sensor.

 

I was thinking that i could just splice into the power wires on the connector peice and toggle it via the switch in my car. But im not shure that when i switch the botton to off if it will also shut down the temp sensor or cause it not to come on at all.

A lower temp thermostat would probably help more than spicing in a switch.

If you really want to add a switch though, you will have to find which wire off the thermo-switch, and use a diode to isolate it from the wire you are running.

 

I am thinking you could run a wire from your fusebox to the switch, and from the switch to the positive wire on your fan.

 

bad idea, fuse would eventually melt itself if the connection isnt perfect & any of the current touched the plastic on the fusebox the wrong way ;\

You sure? I've seen people run constants from the underdash fuse box to their stuff.

 

Sounds a lil to risky for me but thanks for the idea . Anyone else got any ideas?

 

Bump

 

How about fixing the problem instead of bandaiding it?

And you, stop post whoring for your post count. There's nothing more useless.

It's not a problem. I do alot of circuits and track so i stay in 1/2/ and sometimes 3rd gear and am in constant high rpm's so i wanted a way to cool down my car without it being on. BTW i already see "pop the hood...." and other comments like that coming so whatever if your not helping then your not needed =\

D's on the prowl.

Do you have AC in your car? Instead of splicing wires and ******* with your radiator fan you could add a 2nd fan instead. I'm actually going to do this in my turbo EG.

I was going to use my AC fan, but there isn't enough room, so I have to order a slimline.

Basically what you do is mount the fan where your AC would normally be. You run a wire from your underdash fusebox to a switch (or wherever you want to draw current from), and then run a wire from the switch to the lead of the fan, and then you simply ground the fan on your chasis.

That way you won't be pulling hot air into the bay (as air coming from the rad fan has to pass through the rad. Open your hood after you run your car hard for a bit, wait for the fan to come on and put your hand behind it. Warm, huh?)

Instead you get cool air being pulled into your engine bay with or without the car moving. And since its wired from your fusebox (or other constant) you don't have to worry about having the car on.

 

yeah im sure some melting would occur bc i've seen it happen before unfortunitly.
