most vehicles wire the dash lights in with the rear stop lights to warn the driver of the problem they cannot see. check the fuse for your rear stop and tail lights. had this problem on my vehicle too.
Check for obstruction in front of radiator/condenser that would cause loss of airflow through the core.Sometimes these cores get clogged with bugs or debris and airflow is deminished. The reason for overheat with A/C on is that the condenser adds to the heat in front of the radiator and if there is not enough airflow then the engine also runs hot because radiator can not be cooled sufficiently.
hope this helps
I too, once owned a '95 z28, fun car to drive, anyway HO chevy small blocks w/EFI are notorious for being beasts on a cold start. Try this when you get ready to start the car turn the ignition on but don't start let it set there a few seconds you should hear the fuel pumping waking up. Now instead of holding the key and letting it crank and crank, just hit enough to let the engine fire. Not only will lengthen the life of your starter it will lengthen the life of the fuel pump.
