The passengers side heated seat on my 03 TL-S does't work and the switch doesn't light up. Is the switch light out or is this a fuse issue?

Please help

 

IIRC, both switches are on the same fuse, so that should eliminate the fuse problem, if the driver's side switch works, but check the fuse first, and if the fuse is fine, try switching the switches (driver side to passenger side, and vice versa)

If the driver's side switch works in the passenger side, then it's the switch!
