2022 rear heated grips not working - where's the fuse?

I purchased a 2022 RTL this year and they forgot to install the switch for the rear grips.
I took it to the dealer and they installed the switch.
I tried to use it and it did not work.
I'm thinking they did not put a fuse in. Does anybody know where the fuse is for the rear handgrips?

I had the same issue, and when the new dealer went to install switch they also discovered that the factory passenger grips did not even have the heating element installed.
After they installed the switch and no heat they started diagnosing and found no heating element. So, you may not be losing your mind, you may not have heating element in the passenger grips.

Second what Brent said. During that time frame, some Spyders were shipped with missing key components, such as instrument clusters, tail light assemblies, and heated passenger grips, among others. If a machine was shipped without the switch, it was typically shipped without the heated grips, too. The retrofit kit included both the heated grips as well as the switch. That’s based on a review of history on this site, as well as a blurb in one of Smoak’s videos. So, could you still have the standard grips?

Anyway, all that stuff comes off the Load Shedding relay, through the 25a fuse in the right fuse box.There’s no individual fuse. So, if your front grips heat and your seat heats, then your rear grips should heat. Remember, the engine has to be running to test them.

Mine was shipped with both the heated grips and switch missing.

I will contact the selling dealer tomorrow, thanks
