GreaseMonkey Posted July 20, 2013 Share Posted July 20, 2013 Might be worth checking the Cabin Temperature Sensor (as have had similar symptoms in the past on other cars), located near the Speedo/ Instrument Cluster behind the little grille cut outs in the dash trim panel, might have quite a bit of dust on sensor itself causing it to confuse and over compensate the cabin temp. Or possibly a heater matrix flap servo/ actuator is playing up? if not, just wondering if it has a Diagnostic function, like some of the later Toyota's,(don't quote me on it but from memory, lol!) by holding "Auto" & "Recirc" at the same time with the Ignition in "ON" position?, normal output DTC'S I think from memory are 21 & 24 which are usually solar sensors, so ignore them. or as you say it could be that the climate control unit is knackered.
