its as easy as that

BTW.. meziere doesnt make electric WP for us, do they? Now THAT will cool you down big time in the staging lanes


If the switch is off, and the car is running, the FAN (singular) is always on. took me forever to reach 180*F.. it was nice

If the car is on and you flip the switch, nothing will happen since the fan is already on, and the IC pump is already pumping

 

yah video is working fine, very nice. Now does anyone know how to get both fans to come on?

That what i mean the fan should still run even though the AC isnt on, before the only way you could get you fans to run would be to turn on the AC or via HPTuners.

 

yes you are correct but if your temps do start climbing the other fan will kick on too, i believe.

 

hmm ill be doing this dont really need it but its nice mod to say i have it

 

^^^lol i havent been to the track yet but this will be handy...

 

When you use the two relays you are using, the one on the left is the pump and the one on the right is the fan. The fan one you are using, doesn't that make the fans run at 100%? Atleast on mine if I run the same relays as you did my fans were loud as ****. I changed the relays I am using to use the pump and the fan relay which is below yours (towards the front of the car). That one seems to make the fans run at about 50% so it won't eat up your battery as fast and still moves a good bit of air. I just made up two jumpers, one with a 10a fuse (for the pump) and a 15a fuse (for the fan) and it works excellent. No switch but it takes 1 minute to remove the relays and hook it up. I tried my 15a fuse on the same relay you are using (for 100% fans) and it blew it in a second. So obviously it pulls more than 15a. Im sure you would need like a 30a to keep it from blowing.

I just noticed that yours is an '07. The fuse panel must be slightly different because my fuses and relays do not look identical to yours. Some of my relays are larger. I was wondering why they were different.

 

any way to make the fan run at 50% with the way me and johnny B did it?


I did notice this as well.. fan was loud when car was off (because of 100%)

the car started nice and fine though 10-15 minutes later, didnt feel like it drained any power.

 

If you look at your fuse panel, on the back side of it, it says which relays are the fans. There is two. One on the right (the one he used) and one on the bottom. I am using the one on the bottom so the fans do not run as fast. I'm sure pulling that much power it will take a good hit on your battery if you let it run a good 30 min or more.

edit: bottom being towards the front of the car

 

yes but thats why i only did one fan...so it soes eat the battery as fast as both fans running at 100%... and if you go to the track and do this, you might want to bring a jumper pack bc this will kill the battery pretty quickly. but for only ten mins or so you should be fine.

 

Yeah I am heading to the track next Saturday and the jumper pack is already on the list.

 

Alright I had a problem..............

The balt is at the dealership (great people....probably the best I've been to so far!!)


I installed the IC switch as well as the fans (1 and 2 seperate at 100% each).... Weeeeeellllll Everything was fused; I blew the 10amp fast and 15 amp fast so I put a 30 amp in it....didn't blow. I though Great!! but what happened was that when the car was off the fans and switch worked great......WHILE the was ON.....now this is where I ran into a problem. See when you have the switch off while the car is on you are grounding out the fan/IC pump!!! Which in return blew fan 2 and fried my fuse box and PCM! Like I said before dealership will cover it under warrenty.....which if you look in my garage.....I'm VERY LUCKY!!!! So far they have replaced the battery, 3rd PCM (blew second one too), they will replace the entire fuse box and if that doesn't fix it... They'll install new wire harness!!

So all in all be careful and rethink the switch thing........use the fused jumpers instead

 

i didnt ground them....i said you need to power the grounds! or the pcm will see that the fans are already are on and will throw a CEL!!!

 

Just to make this clear:

I am in NO way blaming anyone....not even you Johnny for what happened....I did this mod willingly and with full responsibility of the after-actions.

Good glad to get that out of the way...You said in this video that you grounded it... http://media.putfile.com/fan-switch-video . If you turn your vehicle on and the switch is OFF....you'll short your system when your PCM puts power to the fans.

 

great video... good job to everyone involved here!! great info

 

Has anyone else had any problems?

 

i installed mine johnny b's way i've had it done for about a week so far so good....hope nothing messes up..explain your problem more in depth ramadi...where did you ground yours at? I put a ground coming from the switch to the center consol. Also, when the car is on i always leave the switch off and when the car is off and I need to cool it down that is when i turn the switch on. I have put about 200 miles on this setup so far.

 

For my fan.......



the switch was run from left to right:

1. left.....positive to power
2. middle....switchable acc to fan + side
3. Right.....ground to a ground

now when your car is off and the switch is on OR off everything works fine. The problem comes in when your vehicle is on and the switch is off. The PCM will provide power to the fans when your tempeture sensore goes above the PCM's settings......so this means that when the fan gets turned on....and your switch is in the OFF postition there will be a short. Try to put a 10amp fuse in there.....itll blow it because it's being shorted out.

BTW Mine was installed johnny's way too

 

Good thread, this is something I want to do also. So many projects WOO!

 

I have had no problems my fan comes on when the car is on and the switch is off and it still works fine. I have drove about 200 miles with this mod.....

 

^^^^put a 10 amp fuse in it......or some 20-24 guage fusable link in there.....I bet it pops it

 

^^^ sorry i have had no problems...

i hooked mine yup to a fuse and nothing happen... i dont know why your cars is blowing that fuse unless the maybe: bad switch, one of the wires are grounding out(cut in the wire somewhere), or maybe you fuse panel or relays are bad, or you could have it hooked up wrong.

did you test where the grounds were on the fuse panel???

 

is it jsut me but when i wired this it seemed like the wires got reallllly hot. and yes it needs a 30a or it will blow anything less. i took it out because i didnt feel comfortable with the wires being that hot, i used 22 gauge and that was to small so i used 14g and it was better but still hot...

i just didnt trust it , was afraid to start a fire, i wired it one wire to ground in console (like video) power to power and neg to relays..

 

silentd <<<<You need to take yours out....sounds like your about to have a fire. I checked all my wires and leads ....everything was fine....of course my vehicle was off. But as soon as I tried to turn off the switches while the vehicle was on ....that's where I was blowing ****.

It's easy for me to understand what happened but it's hard to explain it. I'll try to make a video later tonight about my theory......

 

I may undo it but everything seems fine to me, and no I don't have a fuse in there, but whats the point of adding that whenever everything is fine?

 

m88a, i think maybe you have it wired wrong, something is wrong if you are powering it while the vehicle is "started". it should come on automatically... bc when the ic pump comes on, it will power the one fan on. i think you might have one of the two relays wired wrong. i think you are powering something thats already power and that will cause a problem. example: if you are telling the relay to activated, this will cause a problem. there is only one ground on each relay, and once you power that relay it tells the relay to activated, thus powering on what those two relays power. do you have a voltage tester?
