no a/c runs a little warm

Hey guys went to my parents last night in my 02 Aero, and had no ac and ran a little warm then would go back down to normal temp then rise again and would keep doing this....I kept re calibrating the acc and got these fault codes (1....13, 2...13, 2.... I did look at the list of what they stood for and the 1 is an ACC internal failure.....could that cause the other fault codes and my aero to run warm????

Edit:
Driver side is warm pass and rear blows cool/cold I'm guessing the blend doors are shot as well as the acc but would this make her run warmer than normal??

If Trionic sees an unexpected number from the coolant temp sensor it will disable the AC. Went through this on my wife's 02 when we first bought it. Hers would threw a CEL occassionaly as it got worse.

The coolant temp sensor is inexpensive, located right near the upper radiator hose on the driver's side of the cylinder head.

It's the same CEL, but Thermostat will not effect AC operation.

They are both cheap and right there... wouldn't hurt to replace both, but no, I don't think the thermostat can cause your symptoms.
