theres a wire somewhere in the engine bay going to a solenoid or valve that makes you idle higher when the ac is on right?

the ac doesnt blow cold anyhow so i already disconnected the wire to the compressor that engages the clutch so i dont burn it out or something stupid happen, and it wont slow down the car when its on

so now if i hit the ac button the compressor doesnt do anything-good
the fans come on-good
and the idle goes up like it normally would-DO NOT WANT

so basically i want to disable that switch/valve/solenoid that makes the idle go up so i can use the AC button basically as a cooling-fan button

any help or ideas where to look

 

i want me a fan button haha, tyler suggested that it might just be part of the ecu or something totally electronic makes it rev higher when "ac" is on

 

got tired of looking for crap attatched to manifold and made me a front lip last night

 

anything yall, damn someones got to know

i looked around and i found: a vacum line with a filter thingy that leads to the back of the car, i think its to the evap can or something

also i found a dead dragonfly right on top of my transmission
an acorn on top of intake runners
i wad of leaves on a twig cought in throttle body cables

 

I like have you're having a conversation with yourself. . .

The A/C button on the dash board is a "request" button. It is connected to the ecu. When pressed, the ecu will then check a couple things to make sure that its ok to turn the fans and A/C compressor on. The increased amperage is then monitored by the ELD, (electronic load detector), which then increases the idle to make sure the engine doesnt bog or stall as the alternator is forced to produce more power to drive all the extra components.

So to answer your question, there are 2 things you can do. The first is, dont push the a/c button. The second, snip the signal wire from the bottom, so the "request" will never be made.

What year is your car? Does the windscreen button activate the a/c?

Edit* Just looked at your sig, answered my above question.

In that case, you can snip the wire at the ecu, so the ecu will never see the request being made, regardless of what button is pressed.

 

sounds like a bitch to do

 

umm kay, unplug the freakin relay..... done, fan wont kick on, and the continuity for the compressor aint there, simple son

 

Don't touch the valve responsible for increasing idle, the Intake air control valve or IACV, as it is responsible for maintaining the correct idle speed based on many other factors besides the air conditioning.

Also, yes you could make it to where the AC button does nothing by disconnecting it, but why are you pressing it to begin with if it doesn't work?

SOHC

 

because it comes on when i turn on the defroster for some reason

 

Then turn off the AC and your idle will go back to normal.

 

The AC is suppose to turn on when the defroster is activated. The AC takes the moisture out of the air. Basically, without AC, your defroster won't work to its best.
