would it be expensive to replace the thermostat on a 2003 pontiac grand am
SOURCE: Where is the expansion valve located on a 98 Grand Am 3.1?
Grand Am has an expansion valve. Link below has part number and picture of what you are looking for.

Unfortunately, I do not know precisely. But for the most part auto a/c's are all the same. Below I will describe how to find it. I have also included a aguide to determine system operability that may or may not be helpful. Just trace the system with flow path described below the valve has to be between condensor and evaporator.
Reminder the flow for the a/c system is :
1. From the compressor a high pressure (HP) gas goes to the condenser in front of the radiator.
2. From the condenser a HP liquid goes to an expansion device (orifice tube or expansion valve)
3. From expansion device the low pressure gas enters the firewall to the evaporator.
4. From evaporator the low pressure liquid/gas mixture goes through the dryer
back to the compressor suction.
Below is a guide to troubleshoot and check system function. This can be done by most folks.
Look at the front of the ac compressor and have someone turn on the ac from inside the car. The front of the pulley(clutch) will spin when turned on.
If it does not spin, the low pressure switch (LPS) is not satisfied. Meaning there is not enough freon in the system to operate the system. Means low freon capicity because of a leak.
The LPS can be jumpered to cause the compressor to run (clutch to engaged) which will draw the freon in the system.
The LPS is usually a two wire sensor on the suction of the compressor. (between evaporator and compressor) Unplug the sensor and install a jumper, this will engage the clutch. Connect a new can of freon
and fill to system capacity.
The capacity of the ac system will be on a label under the hood, do not overfill. Probably about 2 lbs. Local parts stores (Auto Zone and Advance) will have freon with stop leak. This may help the leak. They also make a freon with a UV dye. I always add a single can with dye so that if stop leak does not work I can find the leak in the future.
The system should be filled until suction pressure is about 30 to 38 psi..

I think you have 2 issues
It either has a leak & someone tried to
add refrigerant & let air in or your
compressor seal slowly leaks & you may
be able to evacuate & recharge it
It won't work next summer though
Forget the expansion valve unless you had a
compressor failure.
Remove the filter lid (A), then pull out the dust and pollen filters (B).
Pull out the evaporator temperature sensor (C) from the evaporator fins.
Remove the screws, carefully separate the upper housing (D) from the lower housing (E), then remove the evaporator core (F).
If necessary, remove the expansion valve (G). Use a second wrench to hold the other fitting on the valve so the evaporator line won't twist. Leave the first fitting loosely connected so you can use it to hold the valve while you loosen the second fitting.
Reassemble the evaporator in the reverse order of disassembly, and note these items:
