Why is my Toyota Celica overheating, I can sometimes open the cap and that helps

What is your question?

Water pump was changed, thermostat, the heat doesn't work at al. Heater ran out first, then the overheating. Also don't know if this matters but , bulb plugs been melting and turn signals stopped working. Only the sounds of getting to hot.no leaks

What makes this problem better or worse?

Nothing other than driving it so that the air helps to cool it down
