Did a search and no specifics came up - can anyone provide any guidance on diagnosing/repairing passenger seat not heating/cooling? Drivers seat works (so not fuse) and neither blower (napkin test) or heater work on passenger seat. Also the LED does not illuminate. I believe there is a "module" that controls all of this?

Thanks so very much!

 

Can you run a techstream OBDII diagnosis? There are specific sections for passenger seat and driver seat. If you can pull any code, that will be great.

 

Interesting that these data are monitored - can I pull the codes via simple OBD2 reading or does techstream provide these data?

Thanks so much for responding, much appreciated!

 

I am not sure what brand/model your OBDII reader is. Give it a try.

Worse case only the Toyota Techstream software via a windows XP laptop can read such special info.

 

I have 130,000 miles on my 2011 LX and the only problem I had was the drivers seat heating and cooling quit working. Dealer replaced "seat controller" under warranty.
