The heater isn't an extra unit, it is simply pulling heat from the engine and blowing it into the cab. If the engine is not hot the heat will seem like it is not working. If the heat is not working after the engine has warmed up, you may have a fan that doesn't work, or a clogged vent.
If a heater fan is not working on a Toyota RAV4, the problem might be with the blower motor resistor. The blower motor resistor is either on the firewall next to the heater motor or in the dash on the passenger side above the heater core.
hello Can you tell me why the heater on my 2002 toyota yaris isnt working? Ive changed the thermostat,flushed out the radiator and also the heater matrix behind the dashboard is getting red hot as well
What do you mean by "has no heat"? No air blowing out, blowing out cold air when heater is on, blowing nothing at all? Heater not turning on? What specifically is happening?
No one knows if:The heater is NOT blowing - or blowing on high speed only, or... The heater IS blowing, but the air is NOT hotEither way, the "Related Questions" below will get you started
dollars to donuts, if your fan is working and is blowing cold air, your thermostat is stuck in the open position so that your car never reaches operating temperature and your coolant is not hot enough to generate warm air in your heater.

Low coolant? bad thermostat? Heater core plugged, restricted, or airbound? Temperature control not working properly? Water pump not circulating coolant?
The AC switch operates the AC compressor and should have no bearing on your heater function. If your heater is not working properly, you may have a weak thermostat.
