Remove the instrument cluster and take it to a speedometer repair shop. They'll fix the speedo and you can reinstall the whole cluster. Or, do a search on the internet for speedometer or instrument cluster repair. There are several sites that do this.

Explanation of 2003 Toyota Corolla Dashboard
where is the electronic flasher on a toyota corolla 2001
yes
not all Toyota corolla's come with tachometers but if it has one it will be on the left side of the gauge panel next to the speedometer.
a speedo works off speed of vehicle and comes from transmission. a tacho measures engine revs and reads from engine or computer. neither have anything to do with other unless both are built into same electronic dashboard
The dashboard symbols on the Toyota Corolla as well as other vehicles are designed to help you know that your car is running properly. You will find your engine light, oil gauge, hazard lights, and blinkers with your dashboard symbols.
Low tire
It's electronic.

You may need to replace the speedometer fuse. The speedometer cable can cause your speedometer to stop working. The speed sensor can also cause the speedometer to stop working.
What warning? You could try the handbook or asking at the nearest Toyota dealer.
