Heating Issues - Yaris

[dhami]

i have 2004 1.4 yaris diesel. The heating has stopped working. I have had the thermostat changed, but this has made no difference. Does anyone know what this could be or had the same problem?

Maybe the heater matrix is blocked? Make sure all the cooling pipes are warm when the engine has warmed up and try bleeding the cooling system. If you don't get anywhere try flushing the system through.

Check the switch/dial to turn it on and off isn't broken. Many models use electric switches now, rather then just a mechanical 'tap' type of switch. Also, if electric, check it's fuse.
