While having freon put into the ac unit dust/smoke flew out. Mechanic says there's a hole in one or both of the a/c tubes and they need to be replaced. Is this a task that requires taking out the entire unit? What should the cost be? thanks

Do not know what he means by tubes,but there is a evaporator core in the dash in the blower box,and if it leaks,it will have this symptom,the cost can be as high as 500 dollars labor,depending on who replaces it.

What is the poss!ble cause for AC not to fountion

White smoke means the engine is burning oil. Cause of smoke can be worn piston rings and worn valve stem seals. In any event,continuing to drive it that way will run the engine out of lubrication oil. AC not functioning can have many causes such as loss of freon from a leak in the system, burned out clutch on the compressor, failed safety pressure switches ro a burned out relay or a fuse.

97 Plymouth Breeze won't blow cold air due to freon leak.

Your AC system is a closed system, so the fact you have to put more Freon in, means there is definitely a leak. I would check it out with a mechanic.

Emission control

that code has nothing to do with your a/c unit. its saying you have an evap leak somewhere. make sure you check your fuel cap, fuel lines and all vacuum hoses on the engine. also check your fuel filler neck for and pin holes. if you cant find anything, go and get a smoke test done to find the exact problem

I have A 1989 subaru gl I put A belt on the ac unit and put A can of freon in to charge the system it started blowing cold ac for about 20 min but then I think I smelled and saw A light haze of smoke...

i havent seen it only you have but yes it could be a freon leak ,this is what comes of these tins of gas which should be banned ,you must use the proper machine as it weighs the gas ,also it will vacumn the unit so you just leave it connected to the machine for 10 mins and any loss of vacumn indicates a gas leak .simple but these cans of gas cause more hassle than enough also this causes ozone depletetion and selling it through outlets where it can get into untrained hands?? to be be used in known leaky systems .Not a good idea

My air conditioner is putting out cold air for a few minutes then it's warm for 5 minutes and then it's getting cold again? I had the compressor changed by a mechanic who wasn;t sure how much freon it...

OK, the requirement of Freon is 2 for the Cold/Hot problem, a little info first; the PCM controls the AC clutch (adjusts the IAC, Idle Air Control valve to speed up the idle when turning on the AC unit, and slows down the idle after turning off the AC unit), also the PCM controls the relay that cycles the AC clutch. My experience has been that the relay is "going South". This bad boy is in the fuse block in the engine compartment by the Air Filter box. The relay is an inexpensive item, and if you live where the AC unit is used frequently, I would recommend it being replaced every 3-5 years. Be sure to check with the mechanic to make sure he properly recharged the system, and if so, try these ideas.

After approx 40 min of highway driving the AC stops blowing cold

The frosting of the line is normal. Did you use a gauge set when charging the unit? AND, most important, Did you evacuate the system before putting in the freon? Very important.What was your final low side reading and your final high side reading?
