Thread: Common AC Leak Points or Failure Grand Prix

you can use freon with leak detector die in it so where it turns red, you found your leak, then repair where the leak is and recharge it.

same thing happened to me...put die in let the a/c run for a while to circulate the die..never found a leak..but i always lose the freon...however once it gets down to like 15 psi it holds and doesnt go any lower..odd to me lol..im assuming its an o-ring that cant handle the high pressure but can handle the lower pressure.

I had a pin hole leak in my condensor coil when mine was leaking. Look there too!

hmmm..im gonna take my UV light tomorrow night and check there too..thanks for the idea Rynoman

so what does it mean when your car has a/c but absolutely zero heat?

you have absolutely zero freon..or a bad compressor

well on a lazy summer day i'll poke at it a lil bit and see what it is but at least i have a good idea now

WAIT!!! i read that completely wrong. Your car has a/c but no heat? Correct? I thought i read it the other way.

keep in mind i have dual zone, and i have almost heat on driver side and ice cube air on the other. BUT i have A/C. on both sides.

i know absolutely nothing about the dual zone..im assuming its digital since your car is a 99

probably a bad heater control valve, not letting coolant get into the heater core

14.7psi is atmospheric pressure, it won't leak itself into a vacuum lol

/threadjack.

OP, if it's coming out to the point where you can hear it, i would imagine you could see the UV dye or notice a pretty big hole. a bad compressor would lead to no cold air, and it would also sound like sh!t. if you charge it and it blows cold, you probably just have a major leak instead of a broken part. you could try replacing the lines going in to and coming out of the compressor and then pulling a vacuum/charging/see if it works. just check all of your parts really well to make sure the leak isn't in the condenser, etc. i'd hate to do the same job twice

No Prob basically just follow the lines with a uv light and glasses wherever it goes you look. I hate HVAC BS. Mines not working again. Last time i had issues with it, it took me 600 bux to get it right again.

keep in mind that gauge pressures don't tell you a whole lot about the amount of refrigerant in a system just because of the nature of gases. if you really wanna test to see if you're low on refrigerant, open all the doors to give the system an infinate cooling load and listen to the compressor. if it cycles on and off quickly, you're low on refrigerant.

HAHAAHAHAH WOOOOOWWWWW...no wonder, thats makes perfect sense..i NEVER thought of that...so long story short..im loosing ALL my freon lol..im soo dumb for not rememerbing that atmospheric pressure is 14.7

Sh!t my compressor won't even turn on right now lol. But i'm not gonna hi-jack your thread man. Good luck!

if you paid 600 bucks to get it fixed and it's not fixed, they owe you lol

This was done 5 years ago man. When i bought the car in 05 the a\c didn't work. I got it going later that year.
