My ac in my 2006 saturn ion blows cold air when its under 80 degrees outside but when its over 80 degrees it will blow warm air sometimes and cold sometimes what could be wrong with it

You need to fix the coolant leak, then refill and bleed cooling system, then you will get heat and cure overheating problem too

How do you check an orifice? Oh the high pressure side it will be warm to hot to the touch. The cold low pressure side will be much colder 45-50 degrees. if there is little difference and the charge is good the orifice could be plugged.

Some times we overfill the system when charging it up if this is not the case then go back to the tech...oh and check your relays, they are under the hood in a fuse box and marked you will need a precision screw driver set to do this as you will need to carefully uncover the relays if you are not sure that they are making a clicking sound which indicates that they are still good. there are high and low speed relays or it could be your check valve acting up. In any event go back to the tech if not sure what to do.

My guess is that one of the hose's has a leak and needs to be replaced. A mechanic can run some tests to check if that's the case. Best of luck.

I would make sure the shut off valve between the cold air and warm air is engaging. this is controlled by a vacume

TX valve freezing?

if the AC is blowing worm air you need to get your AC recharged if you have alredy done that you should get the compressor checked (it sometimes seazes up or the cluch on it will seaze and you will need to replace it

i hope this helps

AC system appears low on charge

Most likley needs to be recharged. Shouldnt be low, but if it has ever been in an accident it may have a leak or your mechanic stole the refridgerant when it was cold outside and you didnt notice untill you turned the ac on.

PROB NEEDS 2 JUST BE RECHARGED. BUT STAY AWAY FROM THE DEALER. IT IS ALWAYS 3 TIMES MORE THAN A PRIVATE SHOP
