My first post! I have a new (to me) 07 LS460 with climate driver and passenger seats. However, the passenger seat climate (heat/cool/ventilate) doesn’t work. The dial switch doesn’t even seem to have power - it doesn’t glow at night like the driver’s seat. I’ve checked the fuses under the passenger footwell, they all seem fine. Raising the seat and looking under it I don’t see anything obviously disconnected.

Anyone have suggestions as to where I should look next troubleshooting? I heard there may be a relay to check, and that the dial switch in the console can be accessed and replaced somehow.

I don’t want to go crazy trying to fix this - it’s nothing critical - but I am willing to put my own elbow grease and some money into it. Just not sure what to try next. Appreciate any info!

Thanks, Sloan

 

Unbolt the four floor bolts and tip the seat back. Use a Meter to check for voltage at the connector. You can also check the seat bottom fan for voltage. Good time to replace the air filter under there too. If there's voltage, the heating element or fan may be bad. A quick way to decide if you'll spend any more time or money on it.
