Driver's seat bottom and back both get toasty when I hit the switch. Passenger side seat bottom heats up, but back remains cold. Can't seem to find info on how to diagnose and fix; any pointers?

Thanks, all.

 

The passenger seat only has a heater on the bottom. Only the driver's seat has a heater on the bottom and seat back.

 

Sheesh, really? Weak. Guess this kind of thing is to persuade people to get an Acura instead…

Aw well. Thanks for the answer.

 

No problem. BTW, my 05 TSX has only the bottom heater in the passenger seat.

 

Arrrgh…why do they do that?! Doesn't it occur to them that half the reason for having the dang things in the first place is so the driver's spouse won't be complaining about how cold their seat is?!!

Seriously, weird place to pinch pennies. Once the seat heater system exists, the incremental cost for doing both seats fully has to be small.
