Drivers seat warmer doesn't work on my 2000 sc300. Passenger side does work. Where would I start to diagnose this problem? Would prefer to fix this myself.. Replacing the seat is not an option as it is a black leather 2000 in mint condition.

 

Check and see if the seat even has power to the power seats option. If the same is on the other side, start looking through the fuses.

 

Both switches are good as they both light up orange when switched to the on position.

 

Out of all the threads on here, I don't think there is a DIY for this. I at least haven't seen nor remember seeing one.

 

Same problem here...Hope someone will come up with a solution soon

 

This is Club Lexus. Of course we have one.

This is for the LS400, but it could be a possible fix for the SC as well.

Slide, I want to add the aftermarket cooling seats as well... To eliminate "slippery back" syndrome. You think this might be a decent resource? My seats are about a 7 out of 10, but I wanna be careful.

Never really appreciated heated seats until I got to Iowa. Really loved them yesterday, ran errands with the sunroof open, windows down and the seats on. Loving this great weather... More snow on the radar.

Sigh.
