Why is my Toyota Echo heater not working?

Possible Reasons for Toyota Echo Heater Not Working
There could be several reasons why the heater in your Toyota Echo is not working. Here are some possible causes based on the search results:
1. Heater Blower Motor: One possible cause could be a problem with the heater blower motor.
2. Thermostat: Another potential issue could be a faulty thermostat.
3. Heater Blower Motor Resistor: A malfunctioning heater blower motor resistor could also be the culprit.
4. Heater Controls: The controls for the heater may not be connecting properly to the heating system, which can cause the heater to not work.
5. Electrical Problems: Electrical problems in the car could also be a reason for the heater not working properly.
6. Cabin Filter or Vents: If there is a problem with the airflow of the air conditioner, it may indicate an issue with either the cabin filter or the vents. This could affect the performance of the heater as well.
7. AC Core and Heater Core: In some cases, the AC core and the heater core may be passing air simultaneously, resulting in not quite warm air. This can happen if the AC is stuck on. Checking the fuse for the AC and ensuring it is not stuck may help resolve the issue.
It’s important to note that these are just possible causes based on the search results. To accurately diagnose and fix the problem, it is recommended to consult a qualified mechanic or technician who can inspect your Toyota Echo’s heating system and provide a proper diagnosis.
