Possible Causes of Heater Not Working in Lexus GX460
There can be several reasons why the heater is not working in a Lexus GX460. Here are some possible causes based on the search results:
1. Heater Blower Motor: The heater blower motor could be the cause of the issue.
2. Thermostat: A stuck open thermostat may not allow enough heated coolant to flow to the heater core, resulting in no heat.
3. Heater Blower Motor Resistor: A faulty heater blower motor resistor could also be the culprit.
4. Coolant Flow: There could be a blockage in the coolant flow, preventing heated coolant from reaching the heater core.
5. Electrical System: Any fault in the electrical system, such as a blown fuse or relay, could affect the heater’s functionality.
6. Other Issues: Other potential causes include a malfunctioning blend door actuator, defective compressor, or faulty controls.
It is important to note that these are general possibilities and a proper diagnosis by a qualified technician is recommended to accurately identify and resolve the issue.
I hope this helps! Let me know if you have any other questions.

Coolant Level Is Low
If your system doesn’t contain enough coolant, cold air will blow into your car from the heater core. Top off your coolant if you notice that the level is lower than it is supposed to be. If you just recently refilled your coolant and notice this problem, there could be a leak.
