If the pressure is normal, but you're not getting cold air, you may have another problem, like a dead A/C compressor clutch.

 

im sorry let me rephrase that...i get cold air when the fan is kicking in and the compressor is cycling usually when i first turn it on. its when its starts cycling on and off when i start getting warm air.

 

In that case, maybe there isn't enough refrigerant after all. That's getting to the edge of my knowledge, though. Sorry.

 

lol thank you for the help though its most appreciated. im going to go ahead and drain it and just add some new freeon.

 

If you drain everything out, you must add the right type and amount of lubricant with the freon. You can buy R134a with lubricant added.

 

thanks ill keep you posted

 

I'm not gonna add anything productive to this thread because its been covered already and your car is fine but......

I always hear complaining when someone who doesn't know any better asks about NOS
(NOS = a company called "nitrous oxide systems") when what they really are asking about nitrous in general.

NOS = Freon

Freon is a name brand of refrigerant (usually referring to R12), that hasn't been used in years, they have switched to R134a.

Our cars have refrigerant not Freon

 

Replacing the refrigerant will not change the situation...refrigerant does not wear out or go bad, unless you had a burnout in the system. Most likely you have other problems if you charge is correct.

Funny story....Had a lady ask me to do a spring check on her system since the gentleman that had done it for years had past away. When I finished and handed her the invoice she questioned me on why I had not replaced the refrigerant in her system. I tried to explain that it did not need to be replaced. She then told me that "Jim" replaced it every year and that it needed to be changed. "Jim" had explained that refrigerant molecules were square, and after flowing though round tubes for a season the corners had worn off and would not cool properly.....hmmmmmm

 

FYI the word ac is too small of a search word and gets rejected by the search engine. So searching for ac problems, the search brings up posts with the word problems, which is sort of a problem.

 

same here.

 

I temporarily helped the situation on mine. It was cycling an awful lot, on for 15 sec, off for five. Had to remove the clogged cabin filter (at 12k miles). Now it runs for about 30 and off 10, and actually feels a little like a/c. Before the air didn't even feel cool unless the fan was on 3 or 4.

My next experiment involves the evap sensor, and that's my question- how to remove it. I think it has a clip on the evaporator but I don't want to have to pull the whole HVAC apart to pull one dumb clip on a $17 sensor. (Reason being if I need to replace it). In case of curiosity the experiment is based on a few 100k resistors, a switch, and stuff wired in parallel.
