1989 Toyota Celica Repair Question
Heater stops heating
Check coolant level to make sure it is full. If it is, make sure the engine is running at a normal operating temp. From there, check to make sure both heater core hoses are hot with the engine on, warmed up, and the heater on. If only one is hot, flush the heater core. If both are hot, have the blend door checked.
