Sounds like the hig head-pressure cut=out is kicking in and shutting down the compressor. This is probably caused by not enough air being moved across the condensor coil (in front of the radiator). Check and make sure all the engine cooling fan components are in place and functional (fan clutch, shrouding, belts tight) and also check the coil for obstructions (Bug accumulation, road debris, litter). Clean the coil and radiator as much as possible at a self-service car wash, see if that doesn't help.

This can also be caused by an overcharged system (too much Freon). Sometimes when these symptoms first appear, the knee-**** response is to add another can of Freon, only to make things worse. If this is the case, I would recommend a system evacuation and service, replacing the dryer/receiver and pulling a 28mm/hg vacuum on the system, and then refilling with the proper amount of Freon, and cleaning the evaporator coils as well. This can only legally be one by an HVAC Certified technician, to insure excess Freon is not released into the atmosphere.

Hope this helps you figure it out, and good luck!

The air conditioning is running off the power of the engine when you slow or come to a stop the idle of the engine now cycles the air control down cause theres not much power to run the a/c
the more power the more air will be circulated

now i was watching a jeggz infomercial a while back and they mentioned a little device to place on engine that keeps the a/c circulating at same temp even at a stop
some vehicles of higher quality come with this device but its not aftermarket its factory and its not from jeggz
overall you can order this device which name slipped my mind from the jeggz website

You may want to have your fan clutch checked. If the fan on your water pump does not spin very hard when the vehicle is idleing than it doesn't draw air through the condenser and that air keeps the condenser cooler plus it keeps the pressure down on the high side of the ac system. leave comment.

Air conditioning system is not colling the car ? what do Ineed to do ?


i need to know how is not cooling the car?
is the fan blowing air or is the blowing air not cold?
it probably isnt cold.lets try that.
put a set of 134a ac gauges on the system and verify pressures.if it has low freon you may hear the compressor turning on and off.if so for sure its low and you will just need to add freon.
go get a 134a fron fill kit not the conversion kit.
and begin to fill untill the comp stays on and air is blowing cold.then stop filling and enjoy.
do not over fill as this will cause it to not cool again.

Would like to recharge my air conditioning on my 2001 nissian maxima that has 117,000 on it blows hot air when air conditioning is turned on.


You will need R134a, and a filler hose. Charge the system on the low pressure side, it should have a blue cap on the charge point.
Your filler hose will only fit the low pressure side, just in case the cap has been removed.

The air conditioning,the blower fan everything stopped working, on 2002 Nissan Sentra. Does anyone have any suggestions?


One suggestion. Have you checked the fuses ?

I would check the AC or blower fuse to start with. If you have the drivers manual it will show you where the fuse box is. Typically there are at least two boxes to check. One in the Engine compartment and one in the passenger cabin.

Look inside the lid of the fuse box to see which fuse may apply to the AC circuits or the blower and check to see if they are blow. the metal link between the two posts that plug in. If the link is missing you need to replace the fuse with one of the same rating. Make sure you know where you took the fuse out from and put it back in the same slot if its good. Check all the main fuses if possible to see if any have blown and replace if they have.
