The left hand warmer just went out on my '03 Rev. Can anyone tell me what is involved in replacing it? Can you replace it with after-market hand warmer? Can it be replaced without having to remove all the other stuff, i.e., brake, controls, etc. Thanks for any input!

the warmers are built into the grips. they cost around $35 each. I having the same problem with my 03 and am finally going to take it to the dealer.
