Question about 2003 Toyota Avalon

Open Question

'03 Avalon A/C fan not starting sometimes & blowing less always

Several times when I started my 2003 Avalon with "Auto" air, the blower fan for the A/C & Heat doesn't come on, but all displays show everything is working. Nothing I do on the control panel makes it work. Then it comes on by itself (usually after restarting the car a couple of times). Also, the fan blower seems to be putting out less and less air than it used to. I've recently changed the cabin air filter so I know the air flow isn't obstructed. What could be wrong and could the two issues be related?

SOURCE: Installation of 2004 Toyota Avalon cabin filter

I will be happy to provide you with the instructions.

Open the glove box.

Remove all of the contents.

Observe the right side of the glove box door, you will see a black plastic thing/arm that is connected to a cylindrical device; Remove the arm from the glove box door.

After the arm is disengaged from the glove box door. squeeze the sides of the glove box towards the middle, to defeat the 2 stops that prevent the glove box from falling completely open.

Whilst squeezing the sides of the box inward, lower the glove box door down.

With a flashlight, look into the area behind the glove box. You will see a long rectangular device, this is the door/tray for the cabin air filter. Pull it out, towards you. Once it is out, you will be able to extract the dirty filter, and replace it with a new one.

This entire procedure should take you about 3 minutes. Very easy.

Thanks for choosing FIxYa for assistance. A FIxYa rating (4 blue diamonds) would be greatly appreciated! Thanks in advance.

Kia amanti air condition


It could be your blower motor. It is located on the bottom passenger side of the dash board under/behind the glove box. There is a cover you can remove and you can touch the blower motor. once you have the cover off start the car and turn the fan speed to high then try hitting the blower motor and see if you get air flow. if this works you need to replace the blower motor. If not you need a test light and start checking fuses and see if you have power to the motor.

AC isn't working


when a fuse keeps blowing it can only be one of two causes. either the consumer is loading the circuit too much due to a bearing problem or rusty component, or there could be a short circuit to ground. disconnect the blower motor plug connector and turn your a/c on like normal. if it blows the fuse again, replace the blower fan motor. if not, start checking the wiring for any exposed copper that might touch the ground-negative.also inspect all the plug connectors for water damage and corrosion.

Cooling fan blowing relay


Generally speaking, any time you have issues with a relay or fuse blowing again and again, there is a short somewhere in the circuit. It could also be the fan motor going bad, but I believe that is less likely. Does the fan motor spin freely when the engine/key is off? Does it happen when turning the air conditioning on or when the fan starts from the engine coming up to temperature or both?
