how to replace a heater matrix in a toyota previa
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
The heater matrix can be replaced by removing the heater core and temperature control cables. Replace the heater core and the control cables.
it is located inside the heater control box up in behind the centre of the dashboard,to remove and replace the dash has to be completely removed.
Its on the driver side firewall connected between the heater hose. Its a metal valve with heater hose on both sides and a lever on top that connects to the temperature adjustment switch on the dashboard.
air conditioning and heater control
There is no heater control valve fitted on a Ford Escort. The heater matrix is directly connected to the engine's cooling system. To reach the heater matrix, you should remove all the facia unfortunately... :(
behind the dashboard on the passengers side
removing the heater core and temperature control cables
remove radio, heater control, glove box, dashboard trim & bezels. once you do this you can see a tublar bar which the dashboard secured to. remove the dashboard and the heater core is there in the center
Remove the heater control valve and replace it.
It is in the heater box under the dash and it usually means removing the whole dashboard assembly.
