I feel your pain...in my case, I have the button for heated grips ( rocks back & forth between high and low quite
nicely ) but NO heated grips -- apparently, those at the Mother Ship have a weird sense of humor ( no humor like
British humor ).
Seriously, I agree with the fella above who said it's most likely a software glitch; with a bit of luck, the dealer can
bring it back to life with a "reflash" or whatever the geeks call that kind of repair nowadays.
In any event, welcome to the FORUM and good luck!
You have to have the heated grips installed and the dealer turns on the option via a laptop to the bike's PCM. I went through this same procedure after I installed them myself.
