There are a ton of things that will cause an A/C compressor to stop cycling. It's possible that your engine is reaching too high a temperature and the computer is disabling the A/C until it cools down. It is also possible that the magnetic coil on the compressor is getting weak when it gets hot (excess resistance in the coil). This will cause the compressor clutch to disengage for awhile until the coil cools down. If the refrigerant in the system is low, the compressor will cycle on and off at a higher rate of speed ( a few seconds on, a few off ...). The result is usually that the system does not get cool enough at any time. Be careful when adding refrigerant to your system. Overcharging an A/C system can damage the system, and it's dangerous too.

You most likely have a vacuum problem. Could be a vacuum hose or in the dash. Control head has a leak or a servo that actuates the blend air door is defective. It makes sense that when you turn it off and back on it works again. The vacuum leak is enough that when it is running the supply cant keep up with the demand but when you shut it off it has a chance to gain a little vacuum and get the blend air door back to where it needs to be. Like I tell everyone else experiencing this same problem. Go out and drive the car with the ac on max going easy on the throttle, if the ac is working at this point go heavy on the throttle for a few seconds and see if it gets warm. A better test is to go up a hill. When you start up a hill if your ac gets warm that is a good indication its a vacuum problem. If you go back down the hill and the ac works all the way down and gets warm when you hit the bottom and start giving it more throttle it is definately a vacuum problem.

Your evaporator is freezing up like a block of ice then the blower fan cant blow thru it so you get warm air.when you turn off the AC the fan is probably still blowing which defrosts the ice and then when you turn it back on if ices up again.
These happens because a component inside your AC compressor is coming apart and that tiny piece was carried thru your system to your evaporator.
So what the repair will need is a Compressor/ dryer-accumulator/ Evaporator/ an Orifice tube or Expansion Valve.While these things are replaced you should also flush your condenser and your other lines you don't have to replace
This is going to be a very expensive repair to correct this problem i would guess around 1400 to 1800 in cost.
sorry to bring you the bad news

Surely you've tried the Max A/C on your airconditioning knob. If you just have it on AC, then what you say is happening will happen, but if you turn it onto "Max AC" or some similar term, it will always be cool or cold air. God Bless you.

Sounds like it's low in freon (or that R-134 stuff that's in AC's now). Go to WalMart and get a couple of cans...you can put it in yourself.

Sounds like the A/C needs to be recharged.

Sounds like you have a vacuum line that is broken, either that or you have auto climate control...
