I know that the light for the air conditioner/heater controls is one bulb. Remove the two screws on the bottom that hold the front panel, remove the finger slides from their control arms, and "un snap" the panel. You may have to unseat the center air conditioner ducts from the panel. There will be a long clear light defuser that looks like a prizim. remove it by prying one end out and behind it there is the light bulb. Wholaa!

The evaporator drain for a 2000 Toyota Corolla is located on the passenger side of the vehicle, typically beneath the dashboard area.
