Question about 2007 Saturn ION-2 Quad Coupe
Did you have a specific engine code requiring replacement of the Cam Position Sensor?
Did you recently replace the thermostat or run low on coolant or have some other cooling system work done? The temperature sensor can be bad, or simply have a loose wire connection. Check those. There can be air in the coolant system as well. Finally, the thermostat could be sticking and will need to be replaced.
These issues have nothing to do with the Air Conditioner. However, the AC will not cool if the car is sitting still unless the condenser fans (electric) are running. Turn on the AC and check to ensure the cooling fans energize.
Most of these items you can check yourself, however if not, then have your mechanic or a mechanically inclined family member or friend check them for you.

Sounds like a bad ground.
On the back of your instrument cluster is a flat, thin, plastic strip. This plastic strip has thin copper strips in it for wiring. This 'wiring' provides electricity to your gauges, and a ground connection.
(Some gauges have constant power to them, and use the lack of a ground source to provide a reading. Some gauges use the power from the sender unit, and have to have a constant ground source)
There is a ground connection or two, provided by a wire, or wires, from the metal body of your Grand Am. These are screwed to the body by screws that go through an 'Eyelet'. This eyelet is a round terminal with a hole in it. Often the area where the eyelet touches the body, has corrosion in-between it. Or perhaps the screw/s have become loose.
There are also ground straps that come from the engine block to the car body. They are usually at the back of the engine, and connected to the firewall. There must be at least two of these ground straps connected. This is how the body is grounded to the rest of the car. Check these also for looseness, and corrosion.

Sounds like you have a loose wire, probably at the fuse panel for the AC fuse, but be prepared to trace the wiring if the bad connection isn't right at the fuse panel.
Replace the fuse, and see if that clears up the problem.
If it doesn't, measure the voltage on both sides of the fuse so that you can see which direction you have to trace the wiring.
if there's no voltage going into the fuse, start tracing between the ignition switch to the fuse panel.
If there's power to both sides of the fuse, start tracing the wire from the fuse to the AC unit and temperature gauge. Also investigate the temperature gauge itself, as the AC shutoff may be contained within it.
If there is voltage on only one side of the fuse, investigate the fuse itself and the socket in the fuse panel.
