Pull the cover and see if fan motor is running if not see if it is frozen by trying to turn blade if its free check for voltage to it. Its easy to replace yourself.

GMC Acadia AC not working properly


Not sure if I'm too late to answer this one, but you're describing a low refrigerant condition. The hissing noise and constant cycling of the compressor clutch are indicators of that. You should recover the system, record how much refrigerant was recovered, evacuate the system (with a vacuum pump), add A/C dye, and recharge the system to capacity. Common leak areas on these vehicles include the A/C condenser (located in front of the radiator), and the evaporator (located inside the dash, and requires complete removal of the interior dash to replace it). If you can't find a visible leak after running the recharged system with dye for several weeks and it starts to blow warm again, you will need to use an R-134a leak detector to "sniff" areas of the system for a refrigerant leak.

My Air cond, heat and vent doesn't work at all on my car. I have replaced fuses and the blower motor. Whenever I put the new motor in it would run then blow the fuses. Could it be the compressor?


No, the compressor will NOT cause these fuses to blow. You have a SHORT in your electrical system. you have a HOT wire getting into the Ground for that system

Ac unit isn't blowing


It sounds like your freezing up at the coil, which in turn, blocks airflow across coil and only a small amount of air comes out of the vents. This also explains the cold air coming from fan on the outside unit, since the system cannot absorb the heat from the inside of the house through the coil. Your air outside is usually blowing out warm to hot air because thats the heat it rejects out of your system. I would turn the thermostat to "OFF" and turn just the fan setting to "ON" instead of Auto, this thaws the system out faster. Give it time to fully thaw, make sure filters are clean, and check airflow. If airflow is back to normal, your problem is more than likely the charge of refrigerant. If you have to call a technician out, make sure the unit is not frozen at all before they get there, they would not be able to do anything with the system froze. Hope this helps and good luck!

Air conditioner isn't blowing any air through the vents. Compressor runs outside but blower isn't blowing air through room vents


Hello, kindly check your air blower if is running if not u need to call a service technician to check it, if it is running and blow some air, i guess you don't have enough freon to your condenser, (freon is a liquid like a liquid nitrogen that running thru the aircon to create a cold air.Thanks

Sunpentown wa1200e. Feels like blowing cool.


is it possible you cannot hear the compressor running?

Modern A/C do not run all the time even while calling for cool. They do cycle on and off to prevent iceing.

Mastercraft 2.0 hp air compressor will not build up over 25 psi


sounds like a bad or broken valves in the head. crankcase needs a vent which is sometimes a small hole drilled into the oil fill plug and will normally blow some air out the vent while it runs
