Most cars have a check lite sequence at start to prove they work properly. This assures that you'll have a valid indication if the engine overheats. It also means that if the lights don't come on at start that they MUST be repaired.

When I turn my AC on sometimes they come on and sometimes dont, causing it to overheat. I checked the fans by hotwiring from the battery and they turned on everytime.

Engine overheat, low oil pressure, or alternator voltage.

The oil light will always come on for just a second after a car is started. If the oil light stays on, the oil could be low or need to be changed.

If the engine is overheating the temp gauge will go all the way to the right and a red light will come on.
