Heater/air conditioner fan makes noise/vibrations when on

• engine dead?
• car can not drive.?
• battery dead
• fuse blown
• starter dead
• jumper cable starts work?

What you should do is to remove the heater blower motor, it's located directly below the glove box, there are three screws that need to be removed and the electrical connector, usually rodents get trapped in the fan, this is what causes the vibration, the fan is out of balance because the dead animal is in there, not a pleasant task but I have seen this may times

check water pump and all rubber hoses make sure they are tight fitting with no damage .

Sounds like the blower motor FAN cage came lose or broken? could be bad blower motor itself ???

That is where the blower motor is located. It could be that there is some debris (leaves, road dirt etc..) in the blower motor. I'm not sure what kind of smell you are referring to but if that car has sat for an extended period of time I have seen small rodents get into the duct work and build nests in areas such as the blower motor. I would recommend not running the fan (so as not to damage it) and getting it to shop where they can get into the blower motor assembly and see whats stuck in there.

The fan is going bad.

check heater fan for debris,leaves,dead mouse etc etc.

I've had mice in my Nissan PU and actually caught one in a trap set on the floorboard; so I know they can get inside. They also knocked some of the fiberglass insulation into the blower motor so it vibrated as it was no longer balanced. You could have a dead one in your blower. Mine was easily accessible from under the passenger side under the dash. Three screws and the motor dropped so I could clean out the fiberglass.

There is no such diagram. If you wish to do it yourself, snap with your camera phone before you dismantule.

open glove box and make sure that none of the papers from that can get down to blower motor
