With the engine off, check the tension on the serpentine belt. Also, try spraying some conditioneron the belt. Safety first!!! Watch your fingers and moving parts.

when you day the air goes on and off i assume you mean the compressor goes on and off. that is what moves th freon through the system. if you are getting cold air when the compressor is running then the problem is that the compressor is stopping and that would be because a pressure switch may be bad. it is possible that model has a thermal shut down too say if the compressor was low on lubricant and was overheating when it does run. but if it is a pressure switch that is failing and they do, it is an easy fix. if you follow the ac lines you will find the switch.it is small about the size of a sparkplug-attached to the ac line and will have a connector with two wires. if the car is running and ac is on but the compressor is not turning remove the connector and jump to two wires. the compressor will start running if the switch was bad and we are sure there is a good charge on the system. if you are getting cold air there should be a sufficient charge to close the switch. these switches can be removed without losing any freon. there is a valve below them that will shut off when the switch is removed. then all you have to do is get a new one and screw it into place,apply the connector and you are done. if that is the problem. hope this helps please let me know and good luck

Testimonial: "Good advice!"
I have the very same problem with my 99 Nissan Altima. I have replaced both the belt and the tension idler. I believe it may be the AC idler pulley.

I have the same problem start with my 2004 Honda Civic Si today. I checked the coolant and it looks fine. I can see it being the thermostat, but a water pump runs of a belt, doesn't it? That either seizes and stops or it works, I would think, so I'm wondering how the water pumo coild be the problem?
