this has been happening to me the past few days. hot as hell here in jersey for the first time this summer, a few days in a row without rain..woohoo haha. so i went down the shore both days in my black car with black leather and like DIED of heat. i want my ac back. this is what was happening to me, it was turning on for like 5 seconds and then off for 5 seconds and then on, etc. the air was pretty warm. a few days ago, i recharged my freon with a 19oz bottle of freon and it didnt seem to do anything, but the gauge showed that it was in the green area meaning good, not empty and not overfilled. but it read about the same spot before and after i put the can in. do you think i need more? what should i check?

and another random thing is that tonight when it was cooler, the ac compressor stays on for longer instead of just a few seconds, and the air is cool, but not cold. durring the heat today going 80-85mph, the compressor kept clicking on and off quickly....and the air was just not cold at all. but when it was cooler out, the air was cooler but it might just have been cause it was cooler outside...any ideas?

 

if you already have the guages, the check the pressure to se if it still there. run the car for like 2 minutes with the a/c on full. then but the guage on and see what it pops up to. if the guage has dropped and is at nothing ro close to, then you have a leak somewhere. thats what happend to mine. my short ram intake rubbed a hole through it. check for holes all along the ac lines, just follow them and look for anyhting. if the pressure is still there. . then there must be an itnernal porblenm something wrong with the compressor or system yourself. i can try and help you further if oyu find out which path your headed down.

hmmm. i didnt see or hear any noticable leaks. do you think i need more refrigerant? maybe 19oz wasnt enough?

 

test the guage and see if its in the right pressure, if it is then you dont need more its a problem with one of the a/c units. if the pressure is low or gone then you will need more. . .i think that 19oz is plenty. i just used one of the regular kits and it filled it up. just test and fin dout, i doubt you will need more.

 

If you can't figure it out. Take out the entire system and have yourself 3hp and less weight . Sorry just had to add that. Goodluck with your process.

 

that cheap *** gauge isn't really good at troubleshooting problems because it only shows the low side of the system which is only half of the system. There's an a/c high pressure cut off switch and a low pressure cut off switch. Both these switches are used to keep the compressor from blowing up or burning out if there's too little or too much pressure in the system. The only way you're going to properly diagnose the system is using a high and low a/c gauge set. You can look for leaks using a tracer dye and a blacklight and look for all leaks are and fix them. I think I've seen those sets for about 40 dollars. It's a bottle of frean with tracer dye, a set of yellow glasses and a blacklight. You'll be able to spot the leaks pretty easily using that method.

 

Last time my a/c went out was when my short ram intake rubbed a hole in one of my ac lines causing it to leak refrigerant. So, I'd check the a/c lines under your CAI. Prolly have a leak somewhere. HTH

 

yeah... my AC isn't working too cold )= and its fuggin hot

 

Check for leaks around your lines and compressor. Also, if it keeps on engaging and disengaging, your compressor's "clutch" might be f'd up.

 

ac on these tegs suck! I've taken my car in to see if theres anything i could do about my ac...nothing really. The fan is weak, the ac just doesnt blow hard enough, or any thing really cold, etc. I couldve upgraded my cloth to leather, but because of my ac situation, i decided to stick w/ the cloth interior

 

try using the feon with dye to help find the leak. A UV light will be necessary to see where the leak is coming from.

on a related note, r12 is cooler than 138 however, r12 is harder to come by each day as its unfriendly to the ozone.

Good Luck.

i still havent been able to figure it out

the systems s in 3rd gen integras are not designed for the use of r12 refrigent only r134A. using r12 would cause problems and would not be benificial. Have a shop check the high and lowside pressures in your system.

 

i kno 3 things that can be wrong... easy way to fix...
if it turns on and off while driving.. its caused by the high side.. too much pressure while moving.. 3 things can cause this.. evaprator is cloged,too much freon, bad ac pump...its most likely the evaporator tahts cloged.. its around 70 bucks to fix.. its the lil silver canister thing thats on the little hole of your front driverside fender area,

1 little solution is.. release pressure onthe high side of the ac line.. press the little thing in there for about 5 to 10 seconds.. dont push it hard.. gradually make it come out steadily.. if it shoots out really hard and you get freon on you.. you pressed too hard..

The evaporator lives in the air distribution box, buried just forward of your glove compartment.

That silver canister is the receiver/dryer.
