A/C compressor kicks on and then immediately kicks off. We were trying to add freon and the pressure went way up. I stopped, but the compressor won't stay on now.

A compressor will cycle like that when the pressure is too low or too high, since you state that you were adding freon to the system and the pressure went way up that suggest to me that it is over charged. If you dont have a recovery machine to pull the freon out you should have a shop that is certified in freon recovery service the system for you. releasing freon into the atmosphere is illegal and should never be done. I hope this helps.

2001 Chevy blazer ac compressor kicks on then immediately off


Its supposed to do that.
If the system is full of freon, the compressor should start up above 30psi and stay running.
Have you added any freon yet ? What is the high side pressure ?

Toyota avalon A/C compressor cycles on and off to fast


Not sure what the question is - but you have to have the compressor running to add freon.
Most times if it is low you have to jumper the low pressure switch to make the compressor run long enough to add freon.
Under normal conditions, low pressure should be 35-45psi and high side should be 200-300psi with the compressor and cooling fan running.

I recharged my a/c in my 1996 gmc yukon and now the compressor kicks on for a second and then kicks off and keeps dopng this untill i shut the a/c off help


Are you sure you put enough freon in it ? sounds like low presser switch kicking in and out...
The more freon you add the longer the compressor will stay on, when it stays on with out shutting off, stop adding freon.....now if you know there's enough freon in it...you may have a clogged orfis tube, this is like a small filter in the line next to the dryer... its hard to say with out looking at it??

A/c on 97 chevy blazer v6 will not stay on unless I hot wire it and then it still blows hot air. what might be the next thing i check or do to find the problem?


It is probably low on freon. The low pressure switch will turn it off to protect the compressor because it needs the freon to circulate the oil. Hot-wiring it defeats the purpose of the low pressure switch and runs the compressor without oil. If you have not already destroyed your compressor by hot-wiring it, you can probably get it working better by charging the system.

My air condition is not working


first check your fuses and any relays sometimes you have multible relays that are the same in a fuse box that you can switch around but i would bet you have a leak either in your compressor or in your line if the clutch is not kicking on and off or running all the time when you turn it on thats because your freon has leaked out the system is sealed freon does not go bad if there is no pressure in the system it will just blow warm air your question is vague so if your blower is not blowing bad blower motor or a fuse if warm not getting cold your system has a leak if you have not broke the system you can try stop leak 2 cans to seal a leaky compressor compressor could be bad if it wont spin noisy clutch could be bad need new compressor but if a leak after stop leak add the right amount or r-134a 2 to 3 cans if the compressor kicks on on the first can of stop leak or freon your system did leak down and you hope the stop leak fixes it but first check all your lines are tight and that the freon is not leaking from the high or low pressure ports the valve can leak sometimes make sure your caps are on take some spit after you add freon back into your system see if your spit blows a bubble if it does replace or tighten the valve. a few things to check start with power fuses then add a can of freon if you have power now clutch engagement if you add and kicks on there is the reason a leaky system it will all leak back out in a day or several days... thats why you can add the stop leak things you can try or take it to the shop and pay someone some $$$$$

A/c compressor kicks off and on while idling and blows hot until


Immediate thought is a Lack of Freon in the system, or possible failing, of the Low Pressure Switch in the Hose line, that energises the Compressor Clutch.
An inexpensive get out, is to purchase a DIY can of FREON, that includes Compressor Lubricant and inject it into, the High Pressure Freon Hose port.

Just stopped cooling


Need to make sure the cooling fans are coming on with the a/c on. If not need to have that part of the system checked.

My a/c is not blowing cold air. The compressor does not kick on when I turn the a/c on. I have tried adding freon to it but it does not allow any freon to enter the system. I have checked all the fuses and...


The compressor probably isn't kicking on beacuse it is low on freon. It won't take freon when you try because the compressor needs to be running to draw it in. Sounds like a catch 22 doesn't it? There is a low pressure switch either in the filter/drier, or on the low pressure line. If you unplug the switch and hook a jumper between the two pins, the compressor should kick on, allowing you to add freon. Hope this helps...

Air condition compressor won;t kick in


Most likely a loss of refrigerant ( freon ) in the system. The A/C compressor uses a low pressure switch as a SAFETY to insure it wont turn on without freon in the system. Hope this helps.

It will be in the yellow section if the compressor isn't running. Go ahead and hook up the gauge. When the compressor kicks on the pressure should drop to below 15 and then the compressor should kick off. Is it doing this? If yes go ahead and add freon. The yellow section means the pressure is high but you only have to worry about it if the gauge reads in the yellow with the compressor kicked on.
