Why does my corolla have no heat from heaters?
With the engine now hot, both those hoses should feel hot, if one is much colder it means there is no flow going though. It probably means the matrix is blocked.

Why is my Toyota car heater blowing cold air?
Some vehicles have a valve installed in the heater core inlet line. If the valve is stuck closed, that may also answer the question, is your Toyota car heater blowing cold air.

Why is my Toyota 02 HL running cold air?
