2003 toyota echo, rear window defroster not working

SOURCE: 2003 Toyota Echo heat not working. Fan, but no heat.

There is a valve on one of the heater hoses that allows heated water to flow through the heater core when you select heat. With heat selected and car warmed up check to see if both of the hoses feel warm. If not then water is not flowing through heater core and valve may need replaced or heater core is stopped up.

SOURCE: How can I test the coolant temperature sensor on a 2003 Toyota Echo so that I can make sure whether or not it's working properly? Thanks for your kind reply.

Use a multimeter to check. unplug the sensor and replace it with multimeter. As the coolant warms you should see a voltage change. I don't know the exact figures you should see but it works on voltage change to close and open the circuit, hope it helps.
