Most of the time you're a little low on freon...u can get a gage and a couple cans of freon for about $50 bucks at Oriely's. Make sure you're coolant level is good too....sometimes a low coolant level can cause your AC to cool intermitantly...I've had that problem...and if you can't keep the coolant level where it needs to be without is boiling over, then you have a bad thermostat, that's just a matter of a new thermostat, 4 botls, and a new gasket...hope this helps!

SOURCE: air conditioner blows cool air

Start by recharging your system. If you want to do it yourself. Most auto parts stores and hardware stores have recharge kits. Purchase a kit with a gauge to prevent overfilling.

SOURCE: I have 2003 gmc envoy my front ac control does not

Need to check to see if the blower motor is running.If it is,but not threw the vents,most likely a vent door actuator motor.The actuator motor in this case would be bad,it is hard to get to,unless you are mechanically inclined,You can do it your self.If the blower motor is bad,just replace it.Check fuses first,and the blower relay.If I can help,let me know.

SOURCE: AC compressor will not turn on, and will not blow

open fuse panel under hood and check the AC Comp fuse. If it blows again you may need a new compressor

Driver side blowing warm air with ac on , passenger side cold...2007 Impala

The 2 vents on the drivers side have warm air blowing out. ... But a system that is 1/2 pound low will cause the passenger side vents to blow cool or cold air, and the drivers side to be less cool or even warm on this car. There is simply not enough freon capacity in the system to cool the air to the drivers side.

My AC some times blows cool air with good pressure but most of the time blows air with low pressure. I have checked the AC pipe also. Its cool.

I'm wondering if it's NOT the AC but the blower fan, how does the heat side blow? if it's good on all blower settings then, it's more than likely your blender door is not opening and closing all the way. When the blender door stays open a little bit it'll let warmer outside air mix with the cold AC air causing it not to be as cold as it should.

A local garage mechanic says the clutch has stopped working on ac that is why it blows hot air instead of cool says it will cost $900. to fix cause I have to buy the whole ac unit does this sound correct?...

have you tried charging the ac system? most ac compressors have a pressure switch that will not allow the relay to engage the clutch if the coolant pressure is low. $15 can of r134a and maybe a $20 Haynes manual is well worth the price difference, eh?

What powers the cooling fan motors my ac is not cooling properly the motors come on, but they are not turning fast enough. got straight power to motors, they both work ok.

you may find that the cooling fans only run at half speed when the a/c is on they might be set that way & run at full speed when the engine starts to overheat (in stop & go traffic) the a/c may need regassing that's why it is not cooling properly.....hope this helps...... cheers..

AC cools then blows hot air, tempature needle goes up & down

Sounds like the thermostat is trying to stick,and is causing the engine to over heat,therefore condenser is not cooling the freon down enough to cool.Have the thermostat changed and the cooling system bled out,this is most likely the cause.

Ac cooling but not blowing very hard

The AC filter of your car should be under the dashboard on the passenger side. While you have it opened it would be best to go right ahead and have other components clean to save you time.

2002 Lincoln LS V6. AC blowing hot air but sometimes it works fine and blows cool. Is it a sensor problem?

its probably the compressor cutoff switch cutting your compressor off at the wrong time and causing your ac to blow hot. that switch is under your hood right on top of the engine easy to get to. I hope that helps you out!
