heated seats

is there a way of giving the heaters on the seats more power, my touring is really not heating much even on full power, just drove a 2019 civic touring and the heated seats were so hot that i had to lower the power from 3 bars to 2, on my accord even at 3 bars it takes time to even feel some heat coming on and i had complain about it at the dealer last year and they sais that everything was ok
