Have a question on wiring the a/c to my fans!

[Globe891]

on my s14 Sr20det, in my s14, Got the a/c working perfectly utilizing stock lines and compressor :coold:

however, i'm using the Isis duel efans and they have been working perfectly. They are temp controlled, using a fan relay from autozone. That relay comes with a line out to wire the a/c directly so that way the fans turn on when I turn on my a/c, but when my friend and I did it, it just popped a fuse =(

So what have the rest of you done to get your fans on while the a/c is on? I hate having to wait until my fans turn on to get the a/c to blow cold lol

thanks!

You need to wire it to the factory connector by the fuse box.

ah, i'll have to try that out thanks man

^^It makes sense b/c that's where the ECU-generated signal to kick the condenser fan originates... and there is already a relay so you can wire the fan directly to it.

I personally would recommend an additional, small fan mounted to the condenser for this; and leave the e-fans to handle the 'normal' stuff=)

On that note- I use a clutch fan with a separate e-fan to handle my AC, so hopefully someone with AC & efans will chime in.

yea i dont want to have to add on another fan lol but i'm sure that must work exceptionally well! once my fans kick on when the motor heats up a bit it's like a freezer in my cabin lol


also, do you know why only full blast works? my friend mentioned something about a resistor but i figured it was inside the actual control unit so i went ahead and bought a working used one but when i plugged it in all it did was just work on 4 again =( i was a bit dismayed lol so is there something i can replace to that way my gf is not a Popsicle?

^^The blower motor resistor is located right behind your glove box. When you pull the glove box completely down, you will see it right in front of you, with an electrical connector & 2 8mm bolts holding it in. It's bolted right to the blower motor housing.

It handles switching between fan speeds... Also, sometimes, the fins on it (you will see when you get it out) make contact with the structure inside the motor, causing it to ground out and only work on high.... If this is the case, figure where it is making contact and grind the fin(s) down a bit with a Dremel. Easy peasy.
