air compressor: I am talking about the air conditioner in my s13. It was working fine before, pretty cold. Today was hot as hell so I decided to turn it on. The A/C button, when pushed in, the LED will stay on but goes off after 2~5 seconds, during this time I can hear the compressor engages and I can feel the vibration from the shift knob. After the LED goes off the compressor turns off and the vibration is gone. After about 10 seconds the LED come on again so does everything else... the cycle continues. I was hoping it would be low on coolant pressure but according to the FAQ section, when there isn't enough pressure the compressure will refuse to start.
What do you guys think?
A/C air compressor engages but stalls

Actually when your low on refrigerant the light will go out. There is a sensor that picks up if the system has enough refrigerant in it. When you install a new A/C system the light wont go on because its not fileld once you put stuff in the compressor though it turns on. But if it ran cold the day before I would assume its fine.
If the compressor doesnt screech your ok. Just try filling your lines up. But make sure to get a meter to see how much is in there actually.
Other than that you can try and recondition your compressor while its empty if it is empty. Just unhook the compressor empty the oil by letting it chill upside down where the compressor lines where hooked up once that is empty. Fill the oil up to the amount specified by a FSM or otherwise. Then rotate the pully and clutch you should hear some glug glug glug glug noises that means the oil is getting circulated in. Get new o rings for the compressor hookups and lubricate them then reconect the system.
Make sure to rotate the assembly otherwise you could hydrolock the compressor it will screech and stuff.

depends if it screeches it could be hydrolocked or had gotten something in it. We dropped a new d15 civic engine in my friends car during th sumemr when it was humid b4 the A/C worked but after it screeched. So im going to assume he got some moisture in there. easy to fix just drain the oil and refill her and turn the clutch and pulley so it goes glug glug glug.
But if it is truely ****ed up then you need to replace it. youll know when it screeches btw it has to be the worst sound coming from an engine bay ever heard like grinding metal and someone screaming because they are taking a diarhea in the toilet.

If nissans light goes off when the compressor is low on charge this is the first time I have heard of it. On domestics at least the a/c light will always be on unless you have an electrical problem.
As for the timing belt screeching, it is possible but doesn't happen very often. Usually if a belt is screeching it is one of the accesories.

Trust me this "screeching" is most ungodly noise you have ever heard in your life its horrible. You have to plug your ears if you are standing near the engine bay that is the kind of screeching Im talking about. Not a sissy belt screech.
Well its from my understanding pre the manual that if you install the A/C and there is no light till it is charged then it would affect it the other way. If there is no charge the light would turn off. ITs not rocket science its jsut a signal that lets the system know if its charged or not.

If the compressor is siezed and screeching as xxtrizz is saying, then it will smell horrible and be extremely loud.
As far as the low pressure switch is concerned I have never seen one turn the light on the dash off when there was a low system charge. It is possible that Nissan designed it that was, but the majority of cars the light functions independantly of the low pressure switch.

Most but not all. I woudl guess in conjuction with your assumption about Nissans that it is directly related. They had like a little side note. ( Note: A/C light will not turn on unless system is charged) scared me when the A/C light didnt turn on but when I filled it click came right on.
I havent run into that smelling issue yet. With it being seized and all. The two compressors I ran into that had screeched where my brand new compressor and my friends civic compressor. They screched bad, but didnt smell. We got both to work again after they screeched hardcore. Maybe the "no smell" is an indication of a non seized but a hydrolocked compressor? THis would be a good discussion that way we could come up with a indicator of a actually seized compressor.
I think maybe the smell is the main indicator of a seized compressor. since I didnt experience it with the two I worked off of.
