Sounds like something inside blower fan that should not be there , higher speed causes outward force inside so that whatever is in there is forced against the blades and therefore is not as loud

Turned on interior fan speed and heard a loud noise, then nothing. Air speed now doesn't work.


More than likely the squirrel cage fan attached to the blower motor has broken or come apart causing it to bind up in the housing making the vehicle blow a fuse. Check the fuse block for the blown fuse then try the switch for the fan speed again if no noise, you may want to inspect the fan for damage.

that depends on if you think the noise is coming from the motor, or the actual road noise that comes with driving , its probably the same at both speeds but sine you have less air and outside noise,, you hear it more at lower speeds. does it make the same noise when started but not moving? if you answer that yes, then its something else besides road noise, if it is no, then get your front end checked, it could be anything from a bad alignment to a bad wheel bearing, or bad brake ,

I have ran into the same problem, there may be something has got into fan cage. remove fan motor and investagate to see if it is blocked, or if fan is going bad. it is behind glove box, to remove. remove lower right dash insulator panel from under glove box. slide bcm aside for room to get at fan motor. remove 3 screws from fan motor, and remove fan after disconnecting wiring. the blower motor resistor is beside fan motor. the resistor will make ya lose 1 and 2 speeds. for it is a 5 step resistor.

Cooling problems


It sounds like everything is working properly. The temperature will go up when idling. The wter isn't being pumped through the system as fast. When idling, the engine runs at around 750 rpm's. When driving, even at low speeds, the engine speed is at least double that. Make sure your antifreeze is set for at least 20° below zero.

Heater fan motor


The fan motor can be checked by using jumper wires. remove the wiring connector from the fan.Run the positive wire from the battery to the positive on the fan and the ground to ground. It should turn smoothly and at normal speed at 12 volts.If it is slow and noisy, the bearings making the noise. This indicates the motor is bad.
