SOURCE: saturn ion,sometimes wont start
The problem is in the ignition - the grease gets thick in the cold and doent turn quite right the first time. everything turns on, but the anti theft system thinks you have the wrong key so shuts off pwer to the starter. it takes 8-10 mintues to reset. That is why it normally starts when you come back later. I have had the same problem and done tons of reseach. Right now my temp solution has been a small heater and an extention cord. I keep it plugged in over night on a medium setting - just enough to keep the inside temp above freezing. I am also researching remote starts because saturn dealership charges $250 to replace the ignition, and a remote start will run about $300. Saturn wont do a recall because they feel it is not a safety hazard. I say that is bull. Good luck!
SOURCE: saturn ac wont blow cold air
check cooling fan operation while ac on.If fan is working proper,will probably have stuck exspantion valve.
SOURCE: air condition blows hot air but it has freon
You may have created an over charged condition and at this point the a/c compressor will cut off on high head pressures. This can be verified by installing gauges to the systems high and low side service taps and reading the pressures.An overcharged system will start the compressor briefly but soon cuts off once pressure goes to 350 - 400 lbs on the high side. Acceptable pressures for this system should be no greater than 250 high and low suction should drop to 40-50 psi.You might recover the charge and evacuate the system,then try bringing the charge back to proper level.A sight glass in the reciever drier really helps determining proper fill.Once all bubbles have dissipated from the sight glass during charging ,one should stop at that point to avoid overfilling.Too much freon is worse than a low charge especially in hot ambient conditions....

you probably got a blockage in the a/c system,take it to a shop,,,or a bad txv valve
SOURCE: In my 2000 Saturn SL1 I am experiencing very high idle
You could try replacing the idle air control valve but I would obtain one from a local salvage yard, its cheaper and you are not certain if thats the problem, another thing i would check is your intake manifold gasket where it meets the cylinder head, if tha gasket is cracked or leaking it will allow excess air to enter the engine and make it idle higher, the easiest way to verify this is get a can of carb and choke cleaner and spray it all around the intake gasket area, if the engines idling characteristics change drastically then the gasket is bad and needs to be replaced if theres no change in the idle I would start looking for vacumm leaks and the idle control valve issue, which you specified.
