Picked up my wife's 2003 SC430 yesterday from having a routine service. I have now noticed that the light on the driver's side seat heater control won't turn off when you turn the control dial to off. When the dial is in the off position the light dims about 50%, but does not turn off completely. It doesn't feel like the seat heater is on when the dial is in the off position. Any ideas about how to resolve this? Thanks

If you have a multimeter ohm out the pins.

OK. Bumping this thread because I have the same issue. My seat heater lamp does not go out completely for the drivers side seat. It only dims slightly when it is in the off condition. It gets brighter when it is on. Seat heater works fine.
I first removed the switch, disassembled it and cleaned everything, re-lubed it and put it back together. The lamp was still on. I then ordered a replacement switch off of ebay. The new set of switches came in but had the same issue.
So, at this point I am thinking that it is the "Seat Heater Relay" P/N 87501-OW0100. But before I go ahead and order a replacement, I was wondering if anyone else has had this issue and resolved it. Thanks.

I have the same issue - but on the passenger side. I’ve replaced the switch panel but no change.

did anyone solve this one?
