Heater vents close and it sounds like blower motor gets louder when passing gear is used

There are several possible reasons why your blower, vent, defrost, AC, and heater might stop blowing air:

1. Blower Motor Failure: The blower motor is responsible for blowing the air through the vents. If the blower motor fails, you will not get any airflow from the vents.
2. Blower Motor Resistor Failure: The blower motor resistor controls the speed of the blower motor. If the resistor fails, the blower motor may stop working or only work at one speed.
3. Fuse or Relay Failure: A blown fuse or faulty relay in the blower motor circuit can prevent the blower motor from working.
4. Control Module Failure: The HVAC (heating, ventilation, and air conditioning) control module is responsible for controlling the blower motor and other components. If the control module fails, it can prevent the blower motor from working.
5. Vacuum Leak: If your vehicle uses a vacuum system to control the vents, a vacuum leak can prevent the system from working properly.
6. Broken Blend Door: The blend door controls the direction of the airflow. If the blend door breaks or gets stuck, the air may not flow through the correct vents.
7. Wiring or Connector Issues: Faulty wiring or connectors in the blower motor circuit can prevent the blower motor from working.

It sound like the blower wheel of the blower motor is rubbing the inside of the housing (the smoke). Sounds like the blower wheel rubbing may have burned the inner plastic housing or has come off of the motor shaft inside. Take the blower motor and wheel back out and inspect everything closely I think you will find the problem.

sounds like a mouse attack to me. mice get into the heater vents and blower motor cage and make nests. those can throw your blower motor out of balance, thus resulting in the noise and then the motor just gets jammed and stops operation. but it could be just the blower motor failure it self. have it checked.

What have you checked so far ?
Could be the blower motor, the resistor, a fuse, bad ground connection, or the HVAC controller if you have climate control.

the blower motor is under the hood on the pass side. u have to remove the wiper and radiator bottles and also the head light. than take out the 7 bolts that hold the blower motor in than u have to remove the squirel cage before the motor will come out. or it could be the Blower Motor Resistor.

Check you cabin filter it is under hood on pass side near wiper blades
If the blower motor is running fine and no smell from there.

SOUND LIKE BLOWER MOTOR SHAFT BEARING FAILURE.

Does the heater blow cold air from the vents or do you mean the there is no airflow from the vents? cold air from the dash vents when the heater control valve is set fully hot could be an air pocket in the cooling system. The radiator sits slightly lower than the engine causing air pockets to get trapped in the engine when you replace the coolant. you'll have to purge the cooling system to restore flow to the heater core. No airflow (blower motor inop) this could be a bad blower motor transistor. pin test the blower motor circuit.

possible ignition switch, also need to check ground wire to terminal G200

under the hood of the car on the passenger side you will see a round motor sticking up.thats the blower motor there should be 3 screws holding it in place and one plug to unplug.you lift the old motor out and put the new one in in its place
