but i never completed the turbo. i only put on the fmu and removed it. and now i have a problem like you!, i checked the fuses and still it doesnt work.

 

check on the cycling switch, it might be defected since its function is turning compressor on/off

where is that @?

 

First of all make sure the system is gassed, if there's no gas, the cutoff switches won't allow power to the system. If there's gas, check out the relays (they're beside the a/c fan on a G2, don't know about the later tegs) and fuses/ wiring etc.

Did the belt break by any chance? That'd pretty much stop the compressor cuttin in!

if u check the link i posted, a guy said that if the system doesnt have gas, the compressor should still spin.

to refill freon, which "valve" do i put it in? the one with the H cap or the one with the L cap? tia

The compressor <U>pulley</U> is always spinning b/c it is driven by a belt off the crank pulley. There is a clutch between the pulley and the compressor which won't cut in if the system isn't gassed. The compressor itself cuts in and out as required, You will notice it if it's working b/c it will alter your idle slightly as it does so.

Anyway not too sure about the valves, I usually let an a/c specialist fill mine!

 

Your AC Comperssor might be leaking. You can Go to any ac guy and ask him to put trace die on the compressor and drive it around for like a day with turning on your ac. and go back to the ac guy and he will use his black light to see where its leaking from

 

Another option would be to just completely remove the system. I didnt read if you were from SoCal, so that might be unbearable. But it will really free up some weight and some room in your engine when you need work on that turbo'd monster.

I guess I used my failing AC as an excuse to remove it

 

im going to put in one can of freon first and then see if the clutch engages.

do i put the freon in the Low side or the High side?

 

I am currently having the same problem, don't feel the AC clutch that I usually feel when I turn the AC on. The light still turn green and the belt is still intact, compressor still spinning but not sure what causes it.

Is there a way to check the amount of freon inside? Where can I get those dyed freon?

and just where did you get this freon?

any parts store sells 134-a refrigderant in a kit that'll tell you what you need to know....

 

Ac is weak when turbo'd

just sweat a lil more, or go boostin with the windows down, problem solved

oh, its probably taht 134a then. i thought that they were the same.

 

does any one know the location of the relays or fuses. Or how to test the AC unit for power loss?

 

if your going to charge it, charge it though the high side (the h valve haha). but make sure thats the problem first, you dont wanna over charge the system that'll just screw it up more. youd need gauges for that, better left to someone who knows what there doing.

 

o btw it should still kick on if the charge is low, but its deffnitly no good to run it like that so dont keep doing it cause you might burn out the a/c compressor. hopefully that helps you narrow it down.

 

what is the difference between the low and the high side? wil the compressor kick in when there is ZERO regridgearnt becuase of a leak?

 

there wont be a diffrence where its leaking from sense its all one system, technicly yes, but when it comes down to it a leak is a leak. And ive never seen a a/c system that can tell whether or not it has refrigerant in it, so yes it will kick on and yes that's bad cause the refigerant helps cool the compressor and carrys oil and such.

that is incorrect. do not try to charge your own system leave that to a pro. i am an hvac tech but dont do very much auto a/c anymore. (too seasonal in iowa)

wrong...it will NOT kick in if there's not enough pressure.....has to be within a certain pressure in order to kick in....too high or too low

 

my ac leak is coming from the big hose that is under the intake that goes into the L in front of the radiator.... any suggesttions?

 

EDIT: i just put in 1 can of 134 and the compresser started to spin! and the air was getting cooler and cooler. hah, i only put in 1 can just inciase the hose is still leaking.
