Sounds like what you may have is a compressor clutch trying to quit on you. I have a Honda Odyssey and it was doing the same thing and it too had proper amount of freon. Am not sure how to test that clutch for that issue but eventually it will stop working all together just as mine did. soon as the clutch was replaced, had the cold air back. That's what I would have checked. I hope this gets you back into the cold air soon. Jesus loves you, John 3:16-17 (KJV)

SOURCE: Car AC stopped blowing cold, compressor turns on, Freon at 45

check the thermo control amp, it is a sensor that keeps the evaporator from freezing. I had that problem on my 2000, it's a common nissan problem, google nissan ac problems.

SOURCE: AC has freon (134a) pressure is good. Compressor

Have a code reader or scanner put on the car to erase all codes,this should reset the ac system circuit.Also check the low side clutch cycle switch,it may be the problem.

SOURCE: ac was working fine the

Check the low switch by the dryer or accumulator, its a long narrow cannister,

it will have a pressure switch attached to it or near it. put your, ac on high,

pull the molex off the switch and jump the molex with a wire or paperclip,

if the compressor comes on and the ac starts to cool, you will just need

to replace the low pressure switch, if the clutch does not come on,

check the low switch molex to see if there is 12vlts there. good luck!

Cold air goes on and off on airconditioner om y 2010 Chevy HHR.


Most likely it is low on charge, but AC systems do cycle on and off. If the charge is low the cycling becomes more rapid.

03 grand am ac wont blow cold air


Two things are very likely to be your problem. Freon or compressor. Turn on the ac on cold and see if the compressor is engaging, if it is and stops and goes or if it doesn't. try to check the compression on the low side of your ac, the smallest plug where you service the ac. Or take it to an ac professional to get it refilled or checked. Remember, just because its blowing air, it doesn't mean its working. There are fans inside the car that push the cold air inside your vehicle and most of the time these will work, but that's not the only part required to blow cold air inside your car, the compressor is what makes the air cold.

How do I check the Air Conditioner spark plugs in my 2002 Malibu?


Sounds like it is low on the coolant which causes it to only work part of the time. You could probably take the car to a auto parts store and at least here in the midwest, they can help recharge your freon/R22 so you have a good working air conditioner. If that is properly charged and leak free, then your air conditioner compressor might be going bad, but then you would hear a lot of belt squealing when it wasn't working. Most likely though it is just low on the freon/R22.

By the way, air conditioners don't have spark plugs......LOL

I have a Grand Vitara Suzuki 2008. Aircondition stop generating cool air. what could be the reason. car has 14,000 km and since last check I have travelled 1000 km


AC dead. all the time? truly all times.
1: does the fan blow? full speed.
2: does AC work on a hot day and a cold started engine? y/n
3: did you check the freon pressure, with the cheap refill kit
that has a gauge with the kit and hose.
is the gunge reading zero?
4: you start engine, and open hood and look at the AC compressor.
is the fan belt to that compressor turning, or is the belt missing.
if turning is the AC pulley spinning, that is not just the pulley but the
compressor front part and its main shaft, are they spinning.?
if not the AC clutch is disengaged.
if disEngaged, that means the AC logic box, is not happy.
The AC logic box can shut down the AC for 4 or more reasons.
and to find that , I stop here.
the fsm shows the pins on the logic box to see with logic input is failing.
on my car, its:
1: A/C on , switch is off.
2: fan not on, or power to it dead, no fan the logic cuts the compressor so the core dont freeze up and crack.
3: engine overload
4: engine overheat.
5: freon pressure too high.
6: freon pressure too low.
7: too cold outside, so shuts down , has to be extreme cold, RTM.
at the least. all this logic functions, save fuel and save other parts
from damage. and huge costs.

that is it for today, one more unsolved.

The AC in my 2006 HHR only works when you turn it all the way up. Can I fix this on my own?


is the air very cold or just slightly cold? if its nice and cold then the speed switch or reisitor pack that controls the different speeds is bad. if the air is just slightly cold then your system needs a partial charg and to be checked for leaks and this is best done by the professionals even though they sell these little recharging kits at the parts stores. you have no idea what the internal pressures are which need to be fairly exact to operate correctly. you can also damage your compressor if you put too much freon in the system. also there muct be a slow leak or you wouldnt have the problem in the first place.

Air conditioner only works while moving. The AC stops cooling when stopped and idleing. Anyone know what causes this?


Your freon level is low, and not circulating on slow compressor speeds. Stop by any shop that has a sign stating they work on a/c and they can recharge it for you in a few minutes. Here where I live they charge about $20.00 labor plus a charge for the freon they put in, they sell it by the pound.
