How much freon goes in a 2000 nissan maxima my proble, is when my car is sitting still my compressor cuts off when i start back moving it start back blowing

Sometimes the compressor may not have enough compression when the engine is idling. It could have a weak compressor, a low charge of refrigerant or the condenser fans might be running or moving enough air.

Could be crankshaft sensor.maybe needs tune up,fuel filter.

Heres the problem, this car holds a total max amount of 25oz of feron (1lb 9oz). you dont know how much is in the system now and without gauges to read the highside and lowside you wont know how much to add, they sell the gauge with the yellow and green and red display but its not accurate. you just dont keep adding until its cold because will will damage the system. the right way is to have a certified ac tech to check and charge the system. there could be a small leak somewhere. to recarge the system correctly it must be evacuated and then vaccumed down then depending of how low the system is you add the right amount of oil. then you add a dye and the correct amount of freon to the system. the dye thats added is used to find the leak. when the system gets warm again there is a blue light and yellow glasses used to located the dye which will be where the leak is, after recharging and testing you then use a freon snifer to check all components and hoses for leaks. if this is something you cant afford at this time then you can try to recharge yourself but take note that just because the compressor is not on means its low on gas. make sure to get the little gauge the sell and read the directions so you dont overcharge the system. also dont use the sealer stuff they sell, only buy the freon with oil and dye in it and dont vercharge, watch the gauge they give you, you will be charging from the lowside which is the small valve, the hose will not fit on the highside, good day.

seems like you lost your ac charge or you have a bad ac compressor or both. Can be repaired by you with a little ac knowledge 200-300 dollars. compressor dryer oil freon About 700-900 dollars in a shop.Good Luck!!!

If your a/c system is low on freon then the compressor will not turn on or it could be the pressure sensor

Sometimes there are plugs in the compressor when shipped. Make sure that there is nothing in the compressor where the line attach. How much oil did you put in the system. Compressor are shipped with oil in them. The correct way to measure would be to drain the oil compressor and measure that amount. Then drain the new compressor and compare the amounts. Put NEW oil in the new compressor. Remember the compressor can not compress liquids. It is possible that there is too much oil in the compressor.

For protection of your compressor the system has a low pressure cut-out switch that turns the compressor off when pressure is too low (normally due to insufficient charge). This cycling on/off indicates low freon level. Charge the system and you'll be OK.

Could be one of several things. First thing, make sure your compressor is kicking on and cycling. If it isn't then obviously gotta start there. If it is then you more than likely have freon leaking somewhere. Could be a line, could be a hole in the condensor. The best way to find out would be to take it and have the air charged and have tracer dye added. They would then have you come back in a week or two to check for any possible leaks. The dye will accumulate wherever the leak is occuring. That's where I would start. 

First thing to do is visually see if the A/C compressor is turning ON. Now, because the belt might be turning on the compressor DOES NOT show it working. IS THE FRONT A/C COMPESSOR CLUTCH ENGAGED ? If yes, is it FULL with required amount of freon ? If all this is yes,we are starting to move towards the INSIDE of the car. but thats a good start

2000 maxima is filled with R134, not freon. You don't need retro fit kit. Get couple of cans of R134 and pump it into the low side valve /small fiting, while A/C compressor is engaged. If your compressor is not coming on, jump the low side pressure switch to make the compressor come on and than the R134 will get sucked in to your system through the low side line. The proper way to do this is to put a/c system under vaccum for 15 minutes at least and watch for leak/gauges coming/loosing vaccum. Than pump R134 into the HIGH side valve with engine OFF.
