Remove front grill and bolts holding the front bumper and lights, pull the frame forward and it will give you access to the rad and fan.

2001 rav4 making vibrating noises and smells of dead animal when I turn the heater/ac on

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

Noise and burning smell from heater

Pine needles get into the heater box and clog the heater fan motor's "fan".
You also may have rodents in there,making nests.

1990 Corolla: Air/heater switch works only when set to the highest speed.

Take it apart and clean it out as much as you can. Cleaner ( like lysol spray?) may help. Take the blower motor out-that should be easy to get to-and clean out that cavity.
It is the resistor pack, not the switch, for the blower speed problem. See if you can take the glove box off or out. Look for the resistor-it is somewhere on the heater case, and easily replaced. Only one or two screws that hold it, and the electrical connector, and it's free.

I have a 2003 Lincoln Town Car. Iturned on the a/c and there is a loud noise coming from the passenger side where the heater and ac are located. There is also a strong smell. Any suggestions?

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.

I will be please if you could suggest a solution in this case. My 1998 Corolla 160i GLE suddenly developed a noisy vibration in the fan unit. The airflow from the unit appears normal as the fan speed is...

This is a common problem. It is much more common in vehicles that do not move for several days at a time. It is usually caused by rodents getting into the blower housing and building nests.

The blower motor assembly must be removed to clean out the debris. Here are the instructions for your vehicle:


Removal and Installation

Disconnect the negative battery cable. Remove right front door scuff plate. Remove kick panel. Remove lower dash trim panel. Unplug blower motor connector. Remove blower motor. To install, reverse removal procedure.

Fan works but does not blow hard. Used to blow great, now it seems there is an obstruction or internal vent not operating properly.

I know this may sound nuts but you should check these things first, pull fan motor and look in the squirrel cage, i have cleaned out several gm and dodge blowers full of nesting material like insulation and acorns.....yes acorns...rodents love to fill the fans up as nests...yes they can get in where you cannot tell. next look at the connectors at the blower motor and where the wiring connects to the resistor pack, usually located on the ac case under the hood or near the blower housing. check the connections to se if they are burnt or melted. the resistor pack could be bad also. hope this helps....

2004 Toyota Tundra - mice got into the fan assembly and the motor

I have seen that most of the time rodents will build a nest right in the middle of the fan on the blower motor. Remove the blower motor and clean the blower fan and clean out the air duct from the blower motor while it is out of the vehicle.

The heater will not work in the car when switch for the heater fan is on.makes a funny noise when you turn on the heater fan while driving.

You may have a bad fan motor or the basket on the motor has debris in it. Most times rodents will
get into pocket where the fan is and fill the basket with everything and anything they can get to. Try taking the fan out an inspect it for this and remove anything that may be in it. If this has occurred quite possibly you may have to replace it.

Removalof dashboard

Before you take the dash off, try this: Remove the cover under the glove box. Remove the 3 screws that holds the fan motor onto the blower housing. Pull the fan motor down. Look for the rodent, or a nest. Look up, to see if a cabin air filter is installed, remove it & clean/replace. It would be very difficult for the rodent to get past the A/C evaporator & into the heater ducts, as they enter first thru the fan area. The fan usually traps the rodents.
