Sounds Like Pre-detention, or often called Engine Ping, sometimes sounds like a diesel engine in severe cases. Caused by fuel igniting to early which makes the ping sound. possible cause might be to high of a heat range on spark plugs , or ignition timing is a bit advanced, or just poor fuel quality. That is just off the top of my head, hope it helps.

I would suggest replacing your blower motor resistor bock. Speed 123 go through a resistor to limit the current flow throught the motor therefore limiting motor speed. High speed bypasses the resistor block which is why the blower would only work on high.

Fill up to proper level. If it still doesn't move check drive train.

If you take the glovebox out, you can see the air inlet servomotor on the left side of the blower housing. (SEE DIAGRAM) This is very likely to be what you are hearing. This is a quite common problem. This servo is electronicall controlled. When the HVAC is turned on, the servo is supposed to go through a "full swing" to test itself. Many times, things (papers, napkins, drinking straws, etc.) from an overflowing glove box get jammed in the recirc-air flap right behind the glove box. when this happens, the servo cannot make a full swing and sometimes it damages the servo, which continues to attempt the full swing and keeps clicking because it is stripping its internal gears trying to make it happen.You will most likely have to remove whatever it is that is jamming the door and replace the servo.

replace the A/C relay in the fuse box under the hood.

blower motor bearings going out ,,,replace motor
