I have a 2021 GLS 450 with the rear heated seat package (the middle 3 seats). Does this package only heat the 2 outer seats or are all 3 seats in the middle suppose to heat? My kids are always fighting about who has to sit in the middle seat of the middle row. Its' cold and doesn't heat up... I can't find the answer anywhere! Thanks!

 

that should heat the middle as well.
