Sorry guys. Its not a clicking noise. More of a raddling noise. Like something is differently loose. Can only hear when you are going about 40mph or more.

 

Might also be a loose windshield cowl or seal.

 

Had this problem too. I too initially thought this noise is in the driver side. So I asked my wife and kids to listen carefully and try to locate it. Sure enough, found it to be a cable inside the 2nd row passenger side captain chair. The cable rattles in one of the metal parts of the chair. Found out that the cable got out of the clip. I removed the chair, put it upside down, reached inside the uphostery, reclipped the wire, wrapped around some tape on the cable where it touches the metal part and all good now.

 

Had this issue too and found it to be annoying. I start to hear the sound at around 40 mps as well or when i hit a hump or a bump on the road. Found the issue to be with a loose cable wire vibrating against a metal part of the 2nd row captain chair passenger side. What i found is that there are cables underneath the uphostery that may become loose. to be certain that it was indeed the issue, i tried to shake the cable and make sure it heats the metal part underneath the chair and confirmed that it was! As the captain chairs can be removed, i removed it, turned them upside down, reached inside the uphostery, re-clipped the cable and wrapped around a tape on the cable where it touches the metal part of the chair and porblem gone now.

 

thanks for the reply. Dont think it has to do with the windshield since its coming from the lower foot area of the drivers side, like it was on the left side of the drivers left foot area. Could be even in the front left wheel well or inside....its a raddling sound too and only at high speeds.

 

Did you ever find a solution? I have a very similar problem with my 2006 Sienna.

 

This has been described on Sienna Chat previously as a "tick" noise I believe.

Description

Some 2004 – 2006 model year Sienna vehicle customers may complain of a ticking type noise when driving at slow speeds. The ticking noise may sound like it is coming from the A-pillar, instrument panel, or windshield areas, but the noise may actually be coming from the upper strut mounts to the body.

EPT (Ethylene-Propylene Terpolymer) sealer should be added to the top of the left and right front strut assemblies to reduce the ticking noise. Follow the repair procedure in this TSB to install the EPT sealer.

Applicable Vehicles

2004 – 2006 model year Sienna vehicles produced BEFORE the Production Change Effective VINs shown below.

FWD 5TDZA##C#6S402509
AWD 5TDBA##C#6S056185

There are more details out there is you search on "tick".
