Hello,
I've had a weird noise with a 2000 Avalon for several years now. Never knew it was related
to any specific thing until today.
The noise seems to be coming from the steering column/dash near the radio console.
The noise is controlled by the AC. Strange but if the AC is on and set manually between 70
and 80 degrees the noise starts. Sounds like a vibration, or like the old speedometer
cable came loose. Kind of like a clicking that changes pitch, up and down. Not ear
shattering but annoying.
Now, if I turn the air up all the way to HEAT or all the way down to Cool the noise stops.
I believe there is a small valve that opens or closes according to the setting of the AC
and when this valve, kind of like a butterfly, has AC air passing around it the vibrations
starts.
Any thoughts? Can it be repaired? About how much will it cost?
Thanks for help.
Billy Boy

Does the noise occur while driving, stopped, engine running in park,
ect.? It might be two objects rubbing against each other only at the
temperature range you mentioned. Can you or another get under the dash
to troubleshoot while it is occurring? |

Noises are difficult to diagnose without hearing them first hand, but from
your description, it sounds like one of the actuators for the dampers. It
is a pretty complicated setup, but if you can see under the dash, you may be
able to see the actuator that is causing the problem and give it a shot of
silicone lube.

Also look for mis-assembled ac duct work. I had all kinds of noises coming
from under my dash and I found that duct work design so that the front of
top piece would fit into the bottom piece actually had been assembled in the
opposite manner. This was in a 2001 which is the same design.

Thanks.
The noise occurs while driving, stopped, engine running in park, etc. all the time
depending on the temp. set on the AC. If the AC is set between 70 to 85, the noise is
there. If the AC is set to a lower or higher temp the noise quits. Absolutely.

I will take a look under the dash and report back my findings.
Thanks.

I will take a look under the dash and see what I can see. I will report back.
