I need more infor about your unit, but it sounds like when the cool goes off, the indoor fan continues to run. This would not be hot air, just room temperature air. Check it. If the air is actually hot, either the heat in the unit is also on and you have a heat gain from an outside source.

It only charges halfway


Hey Don, What are you talking about..?? battery, a/c..??
If its the battery. is it a sealed battery..- replace it. If its a lean/acid battery with caps that allow you to check the acid level, check the levels..do not overfill..if all is well - replace it,
If this is a A/C issue, sounds like you need to vacuum out the air and replace it with freon and the correct oil. (try letting out some air - out of the valve where you are putting in freon - PUT A RAG AROUND A SMALL ROUND FLAT NOSE DRIFT(PUNCH) AND PUSH IN THE VALVE.. IF JUST HOT AIR COMES OUT.... you have found the issue....keep letting out air until freon comes out..(I had this same issue.. there was A LOT of hot air in my system.?? ... when I got it out.. the system worked GREAT!! ) - . if freon comes out.. stop!! - get vacuum pump and hose set, and get the air out - (you need an experienced tech for this)

AC has a New AC Compressor, plenty of Freon -it works but, only Hot Air blows through the vents ??? Is this the vaccum hose or the Heater Control Valve?


Check the heater control valve. And verify if there's hot air w/o A/C (fresh air with heat setting to cold)

Cadillac seville w/ 4.6 motor; air conditioning codes kick on when hot.


as I have not seen this problem as you described I have worked on a caddy ac unit before that worked for little while and shut off replaced a few parts but when all was said and done tunrs out it had a small hole in condenser in front of car grille and some of freon leaked out even the new stuff I added


that's why it worked for a while as it took several days for freon to leak out could not have found leak if not for a freon detector I had borrowed from a friend it was that small ! dye did not work

A/c is not blowing cold air in front but air is cool in the rear.


Hey M, the pressure could be nothing but "hot air" and not freon... (I had this same problem!!) I let off a bunch of pressure..(nothing but clear hot air!!) ..using a small flat punch..on the low pressure side... if freon on comes out right away..stop.. if nothing but hot air comes out.. keep letting it out until freon comes out,,, When mine started letting out freon,, I quit and tried the A/C again... and it has been working fine since.. Just my recent experience!!!!

Hello everyone I have a 2004 nissan titan and when I am travelling down the highway the ac blows warm I have checked the freon level and it has the proper amount of refrigerent in it and the clutch fan...


Hey Wb, You say you checked the pressure and its ok. Have you checked to see if the pressure is actually freon or just hot air..(this is from a personal experience with the same symptoms) Let some of the pressure off the system while it is running..(the low pressure valve) and if freon does not immediately come out.- Just hot air..let it bleed until freon comes out .. (mine was overcharged and I had to let out A LOT of air out of the system until freon started coming out).. try this and see if it helps.. ...mine is working fine..blowing cold air 24/7 after this .. with no other steps,,,

Air conditioning isn't cooling at red lights.


Sounds like it is low on freon. I'd throw another can in itif pressure is down.

Ac quits while stopped at a stop light


You do have a AC problem. Your AC doesn't like what is going on and shuts down to protect itself. The front AC fan may not be running and cooling at idle and the higher hot freon pressure causes the pressure sensor to shut the compressor down. When driving you have plenty of air over the condenser. So check it out.

My ac turns on but it only throws hot air it used to throw it cold a few days ago, whats the problem?


Adding a can of freon is not the solution, a system that has too much freon will not work right and there is a chance that you will damage the compressor.
There are low pressure and high pressure switches at work when the system is operating.
You might have a bad switch, leaves or other matter blocking the front condenssor.
Is the system actually full?
It's best to give this problem to a certified A/C mechanic.

AC WON'T COOL


Sounds like you have a freon leak or your compressor has stopped working. You will probably need a service tech. If it is out of freon, don't let them just add more freon, make them find and repair the leak first. Good Luck.
