Hey SOLARSTU,

it sounds like you have a blend door actuator that has gone bad, here is an article that will help you. if you have a manual system check the heater control cable.

My daughter's 2000 Toyota Celica isn't generating any heat. The blower's working & she had a/c working throughout this summer fine. The Temp gauge on the dash seems to respond to the engine temp ok. What other troubleshooting steps could I take to get to the root cause. There isn't any leakage of anti-freeze on her floorboard.

Did you check the coolant level? If level is good, problem may lie in stuck open thermostat.

Hi there,

If the engine temp is lower than normal, replace the thermostat, Check the heater hoses are both about the same temp. If not check the heater tap and the tap controller operation.

Heater is blowing cold air 90% of the time. Temperature gauge is spiking to overheat randomly than back to normal 2sec later.

Have radiator cleaned, bay bed part blocked in the cores restricting circulation, not just a back flush but a full clean by a radiator repairer.

The erratic temp indicates there is air in the system and it needs to be bled out thoroughly. Using a vacuum fill method is the best way to get all the air out.
