I have a 2001 Chevy Impala. The temp gauge is reading at the bottom and won't budge, even after I drive for an hour. Also, the A/C doesn't work and this morning I tried to drive it again and the check engine light came on about 10 miles down the road. Someone suggested the thermostat, any other suggestions?
Have you verified that the thermostat is stuck open? Do you have hot heat inside after driving the car for a while? Is the top radiator hose hot or just warm? If the guage is accurate, chances are the thermostat is stuck open. How many miles are on the car?

Could be a bad temperature gauge or sensor. Could indeed be a bad thermostat. Could be a loose wire or a blown fuse.
The AC is almost certainly a different issue. The check engine light might be a third issue, but get the temperature gauge or the thermostat fixed first.

I would be surprised that the engine stayed cool enough not to even register a temp at all on the gauge. Especially in summer.
Feel the hoses and see if they are hot. If they are then check the wiring on the temp sensor and / or replace the temp sensor.

I suggest you give a better description of the A/C and "check engine light" problems including whether their mentions are supposed to be somehow related to the temp gauge problem.
