SOURCE: where is the fuse box on a 2003 Toyota Corolla?
Hello, welcome to FixYa.
The fusebox for an 03 Corolla is on the driver's side of the dash, above the plastic panel that is above your knees. You can see it by looking up and to the left, under the instrument pane, with a flashlight. It is a rather large white or cream-coloured box (depending on where the car was produced). An easier way to get to the fuses would be to remove the plastic trim panel that is directly under the bottom of the instrument panel.
Thanks for choosing FixYa for assistance today.

I need to get a clear mental picture of what exactly is happening.
With this said, you stated that the car "runs fine" until warmed up.
Q: When you start the car when cold it idles fine?
Q: If you allow the car to idle until "fully" warmed does the car stall?
Q: As the car begins to warm up, Does the RPM fluctuate abnormally?
Q: Does the car Only stall when you press on the gas pedal or does it stall just sitting and idling in addition to pressing the gas pedal?
Q: If you can drive it while cold does the car stall during acceleration when warm or only at Stop Signs / Lights?
Q: If you wait 20min or so, can you start the car again?
Q: How many miles are on the car?

SOURCE: 2003 Toyota Corolla LE back seat fold down? how?!
Open the back trunk, look near the top of the trunk, and pull the two black levers. They have a seat folding down symbol. That will release the locks to fold the back seat down.
