The air tempeture actuator has probably failed, it is on top of the passenger side heater case behind the glove box. When connecting the new actuator have the electrical connector connected put the control head on 60 move the door linkage to the full cold position before connecting the linkage to the new actuator

Toyota Corolla 1987 heater not working when I turn on heater fan on it's warm for about 30 sec then goes cold and the guage goes to cold and stays there


Most of the times the heater core gets clogged or corroded. inside the fire wall and the hoses run through the engine compartment and into the firewall. You can try disconnecting the top and bottom hoses and using a garden hose to flush out debris. Flush through top hole first then bottom cycle back and forth to break everything up and water comes out clear. Then hook the hoses back up. Also make sure that your radiator l with coolant at the proper level. The heat typically coming out warm then blowing cold is low coolant or clogged heater core but the gauge on the dash should only symbolize engine temp. If it stays on cold, you may also want to check your thermostat to ensure it functions and opens and closes as it should. All cheap fixes that can be done yourself.

On my wifes 2004 yukon, the engine warms up and the blower works fine, but it takes forever for the air to finally blow warmly. when it finally does, if we switch it to another location (floor or defrost),...


iwould check the selector motor,and also replace the thermostant,start with the stant first,the selector motor is what runs the door for hot or cold the motor is a common problem,if the temp gauge is showing a quick warm up temp then its the selector motor, if it takes a while to reach operating temp then replace the t-stant,also make sure the coolant is full in radiator,check when cold or warm,dont open when hot, hope this is helpful.
