SOURCE: my ac blow out hot air and i want to put freon in

Adding freon will not correct the problem. If you need to add freon, you have a leak, and you have moisture in the system, the leak should be located, mositure removed, then freon added. But to answer your question. Open the hood on, the left side you will see a round object called a dryer, you will see two pipes coming from it, one at the top and one at the bottom. The smaller is the high side, the larger is the low side. Obtain a can of freon either R-22 or 134a with an adapter for installing the freon. Turn the engine on, turn the AC to high. Add the freon to the ac using the low side.

SOURCE: air conditioner just stopped blowing cold air

Saturn 2000 SC

Your system uses r-134a as the refrigerant. Freon® R12 was outlawed some years ago.
It looks like you may have lost your r-134a. You will have to get it replaced. When you do, be sure
to have an ultraviolet tracer dye added. This will be used to detect the leak you appear to have.
When the system is recharged, your mechanic can take a black light (yes like in college)
and check for leaks. If something has bump against an AC pipe the O-ring seals may be loose and would need to be replaced. The test will show it.

First, check your engine coolant level. If it is low, you need to find out why. If the coolant level in the radiator is full, it could be many things including a bad thermostat, a clogged heater core, or a broken or damaged air temperature door or actuator.

2002 saturn sl1 blows hot air when ac is on heater works idles and coolant leeks out just bought a new radiator still not working


Not sure where to start with this - - if you are saying the engine is running hot could be a thermostat or low coolant or other issues.
The hot air with the ac on could be the ac not being charged or a blend door stuck in one position.
Where is the coolant leaking from ?

I have a 2000 Dodge Ram 1500 that will blow cold and hot air for only a few minutes. After that is only ambient air temps. It is a 5.7 ltr, automatic with only one set of climate controls. The heater core...


you say it will blow cold and hot air for only a few minutes. You don't say but I assume you mean will blow cold a few min. when turned on AC max , blow hot only a few min. when turned to heater hot. Assuming thats the situation and you say AC charged and shows good on the low side -you should charge the AC to a full charge on the low side will cause problems with the AC air compressor kicking on and off. I suggest while the engine is running and turned to AC cold max watch the AC air compressor clutch to see if it does indeed kick on and off if so charge completely. As far as the heater make certain you coolant is all the way to the top and the best way to do this is when engine is completely cold remove radiator cap and fill completely and completely close cap then fill overflow container just to the cold level. That should fix your problem.

Ac blows hot air


If your AC blows hot air, these could be the culprit:

1. Not enough refrigerant for the AC system
2. Busted AC compressor

The ac is blowing hot air the freon charge is good but the ac still blows hot air whats the problem with my 2000 chevy silverado?


Is the compressor kicking on? If not and the pressure is in the normal range then I would say that the low pressure switch is stuck. It is located on the canister right beside of where you hook up the freon. Unplug it and cross out the plug and see if it starts then.
