#76 of 102 12v Power Adapter by sopman

Oct 29, 2011 (5:40 pm)

I have a 2006 Sienna. There are two power adapters on the dash and one in the back. One of the two on the dash and the back power adapters do not work. Does anyone know where the fuse is located?

No one responded. But the Toyota dealership ended up finding it. I don't know the precise relay switch but it was a relay switch under the hood that connected the radio and heat. The crazy thing is just a few weeks ago our dashboard was flipping out. That was another relay switch that needed to be replaced - one that was under the dashboard making a clicking sound.

You're right no one responded.
A switch that connects the radio and heater has something to do with the power adpter?

#80 of 102 Head relay clicking on a 2000 Sienna by chanli

Hello,

There is a continuous clicking sound from my 2000 sienna when it's parked in garage, engine is off, key is out and doors are closed. At the same time I found I can not start the car, and the door light is quite dim.
Later I found the sound is from Head Relay, and if I turn the headlight switch to 'off', the sound will be gone.

What could be the root cause of this? The battery is about 4 years old, and I think it's time to replace, but is the dead battery causing the click, or the click causes the dead battery?

Thanks,
chan

I have encountered the same issue with my 2010 Rav4. Every now and then, the volume will increase for no reason. The times I have noticed this is when I'm shifting into reverse from being in either Park or Drive. My RAV4 does not have steering wheel controls for the radio, so I'm not sure what might be causing the conflict.

My pre-owned RAV4 was a rental car for a year, so I thought maybe there were some restrictions put on the volume of the radio (as it seems to be fairly quiet even with the volume cranked to 20+). But I find it interesting that there are others out there with similar issues.

replace the starter contacts, no need to remove the complete starter, just the head.

Did you happen to get your Sienna Van left turn issue resolved?? I have a 1998 Toyota Sienna van also and when I turn left the map lights come on, the panel shows door ajar (LED) and if the doors were locked, they become unlocked (click noise). Once you straighten wheel and go straight all becomes normal and map lights turn off, etc. This NEVER happens when turning RIGHT.

Any ideas for fixes out there ??????

THanks,

Z
