im just wondering wat i need in order for my a/c to blow cold air,cuz rite now it jus blows hot ass air.....i have 97 altima dual eletric fans on a ka if it makes a dfference....
would i jus need freeon?
 
Could just need freon. Could be your a/c clutch worn, compressor internal failure, expansion valve clogged or any number of things including leaks causing no freon. You could start by filling with freon and seeing what happens or bringing it to a mechanic who has a/c gauge manifold and could tell you your pressures inside your system.
 
try the flux capacitor inside the dalton gauge that might be it

wheres the flux capacitor, would it be near the vtec solinoid?

thanx ill try that

If you're not trained in A/C work then you're better off not messing with things as you can make them worse.

Initial diagnostics should always start with checking to see if the compressor is engaged when you want the a/c to work. If it's not coming on then the next step would be to check the pressures using refrigerant gauges. Pressure over 20 psi should cause the compressor to come on, even if just for a second. Pressures over 250-300 psi may cause the compressor to be turned back off to prevent damage. Obviously, just adding refrigerant won't help you if your problem is a switch or bad compressor. Also, you could have a cheap switch causing your issue but because you added refrigerant, you now have an over-charged system and that will reduce the performance as well.

Make sure that who ever you have does your work, they use R134a and not propane or R12 when refilling your system. Also, make sure they use a vacuum pump (usually found on your good recover/recharging machines) to remove all the air from the system after the current charge has been recovered and PRIOR to charging it back up.

A mix of refrigerants, hydrocarbons or as little as 6% air content in a system that is supposed to be pure R134a can affect the quality, damage your system or put yourself at risk of explosion (propane).

A/C work can be really easy or really difficult. It all depends on how you go about fixing it that will determine how quickly and cheaply you get back in the chill section.

In other words .. no one can pick a part out of a hat and tell you how to fix your a/c without seeing it. It could just need freon or 1 or possibly more out of like 50 parts could be busted.

You need to trouble shoot it.
