My heater is no longer working on just the front driver's side. It blows cool air out of all vent options. The passenger side and all vents in the back blow hot. Coolant level is where it should be, I’ve tried a reset trick I’ve seen online, and it won’t work.

Hello,

It sounds like you have a faulty blend door actuator for the driver side.
The blend door actuator is what controls the hot/cold air mix, and it can fail in stuck to one position.
The blend door actuator for the driver side is located under the dash on the driver side.

I have attached the replacement procedure below for your reference.

Let me know if you have any questions.
Thank you.
