It sounds like the clutch for the air compressor pump or a faulty relay.

The ac in my wife's Buick Century stopped blowing. When I turn it on I hear a clicking sound near the engine.

On this model you may have developed a leak at the AC compressor and the system is low on charge, that would account for the clicking. If the system is low replace the AC compressor in stead of repairing it., it is accessed through the wheel well liner on the passenger side and from under the car. You can buy rebuilt compressors for this car on eBay for cheap, have on on my own Buick and has been on there for years.

1996 pontiac grand am ac will not work

Ok this should be pretty easy... need a little more info... when you switch the control to AC ..have the engine at idle and listen for a "clicking" noise which is the AC clutch. If you are hearing that click and the ac is just not cold ... that is one thing. If you aren't hearing the clutch engage that is another ... so let me know and I can help you with either one, and we'll have it blowing cold it no time at all!

My ac it's working bad, non cold air. I notice the air it's coming out from the top of the panel and from the bottom, looks like the switch stuck, so I can't swich positions to see if the ac is working....

1st thing you can check is to open the hood and have a helper turn the AC switch on and off and listen for a clicking noise from the engine compartment. If you hear this clicking noise everytime the AC is turned off and on then it is likely the AC compressor is working okay which would likely mean your blend door and actuator is stuck or has malfunctioned somehow. In either case they are both jobs for skilled tech's do to the likelyness of having to remove the IP to change them. If you do not hear any clicking noise under the hood then check all fuses and if they are all okay then I would recommend taking your car to a local tech that is AC certified do to the complexity of an AC system. Hope this helps.

1993 accord ex ac not blowing cold replaced compressor last year freon level ok unit not engaging is there an easy fix?

With the engine turned off, test the a/c compressor clutch by applying 12 volts to the contacts. You should hear a click of the clutch engaging, and if not, the clutch is acting erratically.

During a three hour drive back home, our AC stopped blowing cold air. If you stick your hand in front of the vent, you can feel cold air, but it doesn't blow. If you turn the fan up all the way, you can...

Have your a/c pressure tested, the clicking could be the a/c compr coming on and off due to low freon, it will do that so it don't damage your compr when there is none or low freon.

1999 gran prix a/c is blowing hot air, but was working last year. Put in freon and still does not cool

first turn the ac off and then start the engine. you may want to lift the hood so you can hear the next step better. turn on the ac and within a couple seconds not more than 5 or so you should hear a click sound. This is the ac clutch engaging. if you don't hear a click you can double check the compressor has engaged by looking to see that the center of the ac compressor is turning with the outer pulley. if it is not most likely you don't have enough refrigerant in the system. i would suggest getting an ac pressure tester they are fairly inexpensive but this will tell you for certain if you have enough refrigerant or not.
