Well im from over at ls1trucks but no one there could seem to help me, so ill give it a shot here. My problem is when ever I come to an idle my ac shuts off. i checked the pressure and everything checks fine there and all the connections are good. The only way i can make the AC run at idle is if i go into real time tuning and lock the ac compressor in manualy. Any thoughts guys. O and my idle is set at around 700.

When you say it won't come on, do you mean that the compressor clutch will not engage or something else?

6.0vortecchevy

yea the clutch disengages at idle. but once i get the rpm's above 1k it will engage agian.

fleetmgr

Take the clutch straight to the battery, and see how it behaves then. If it still won't engage, make sure the battery is good. If it is, replace the clutch.

Also, check your alternator output.

well is it the same if i can lock it with efi live. since it does lock when i do it with the tuner.

fleetmgr

HMMM! Well, you wouldn't think it would make a difference, but I'd check all the same just to eliminate possibilities at this point.

6.0vortecchevy

so what your say is run a wire from the compressor to the battier and see if the compressor kick on then.

fleetmgr

You got it, 1 to pos and 1 to neg, doesn't matter which way they go.

6.0vortecchevy

Now if it does work, can i keep it that way or is this just for testing.

fleetmgr

Testing only!!!

6.0vortecchevy

Thats what i thought lol. ill go do that right quik.

6.0vortecchevy

okso the compresser kick on when i hot wire it.

fleetmgr

OK, now that you've had to disconnect and reconnect the compressor, what's it do when you try to operate normally - same thing?

6.0vortecchevy

yup right when i put it in back the regular way it went back to what it always did.

fleetmgr

OK...I see in your OP that you've been inside the computer. Do you have a tune in it? If so, what happens when you go back to stock?

Also, need some vehicle specifics.

6.0vortecchevy

well its a 00 2500 6.0 chevy and if i went back to the stock tune it bearly runs. And does the same thing.

fleetmgr

Well, then I'd suspect a wiring issue in the dash. Something making intermittent contact, like maybe the blower switch. Possibly a wire touching something, and vibrations at speed making it not touch...something like that.

6.0vortecchevy

well when im driving the ac works perfect.
