No heat in my 1999 Avalon. Both heater core hoses (in and out) get hot, however, no heat when I move heat/ac control on the inside panel nor when I manually adjust the control on the Heater control valve near the firewall (engine). Also, the cable from the control panel to the Heater control valve does not move when I change the temp control inside the car. The coolant level is good and the temp gauge registers half way between hot and cold (normal). Any ideas of what is stopping my heat?
If the heater control does not move when turning the kbob, that is the cause of no heat. Either the cable is or its connection is dislodged or stuck, that would prevent the air-mix blend doors from turning to the heat position.
