just did this mod and i love it already...its so nice being able to turn on the defrost and all the other settings with out that annoying clicking sound and the major loss of horse power...i definably recommend it. i mounted my switch in my glove box....

 

X2 did it a couple weeks ago. Love it, one of the simplest and most satisfying mods I've done yet. Now I'm just paranoid that if I don't engage the compressor once in a while it's gonna crap out on me. lol

 

would this be the same as switching to the "off" position? did you pick up a noticable gain in hp?

 

ya its the same as when it is off...but i can have it in whatever mode i want and not have the ac compressor go on.....which u can feel it when it goes on. normally the compressor goes on it every position except for all top vents or all floor vents....now i can put it on top and bottom vents and i can use defroster and even a/c with out the compressor going on. also no annoying clicking noise when i have it in those positions where it would normally go on.

 

The annoying clicking noise is the a/c compressor cycling. Some people don't know this, but the a/c compressor kicks in when you use defrost...

 

I guess you lost me on this one. Does the defrost still work without the compressor working?

 

Yeah, I believe it still does... And was this relatively easy to do?

 

I don't understand this mod... got a link for a how-to? I've never seen this in the How-To section (unless I'm blind)

 

here it is

Ooh... so I AM blind.

thankz for the link.

 

How? If you're essentially taking control of the compressor manually and not letting it cycle, how is it suppose to do it's job?

I suppose it doesn't matter really, considering you put a switch in so you can either control it or let it run by itself.

 

The air will still come out the defrost vents as normal, it just won't be the dry air you get if the a/c was cycling. You need to turn the compressor back on if it's real humid or foggy outside, as the defroster won't clear the fogging windshield as well (if at all) without the drier air.

4.0 owners don't have much of a power drain with the compressor running, but others engine owners definitely do.

 

wildbill brings up a good point....

is it even WORTH a 4.0 owner to do this mod? I've NEVER seen a decrease in power when I've got the system running.

 

I also us it in the summer to turn the AC on and off. If i'm on the highway the AC doesn't have to run all the time. I also during the winter turn it on once in a while to make sure that the compressor cycles and oils itself.

 

this mod basically disables the electronic clutch on your a/c compressor....

when you have your Heating and A/C system "on" it tells the a/c clutch to cycle on and off even if you have the heat on full blast.

disabling the clutch allows you to have heat or just a controllable climate in the cab without the A/C compressor dragging down your engine when you're not even using the A/C

 

Why though? The compressor cycles when you use defrost...
