There are many possibilities for no heat.

1. Low coolant.

2. Thermostat bad. It could be stuck open not allowing the coolant to warm up.

3. Heater core partially clogged.

4. Blend door actuator.

5. Engine issue. A failed head gasket will cause this as well.

1. Remove the instrument panel carrier.
2. Disconnect the electrical connector (2).

3. Remove the air temperature actuator retaining screws.
4. Remove the air temperature actuator from the heater/vent module.

That is correct. If you read the instructions, you need to remove the top pad to gain access to the actuator.

Good evening.

It could be from a couple of things.

1. Low coolant level.

2. Heater core partially blocked not allowing circulation.

3. Bad thermostat.
