The grip must have the required resistance, and since they are wired in series, if one is open, neither will work. The most likely place for an open circuit is at or near the grip, so remove the two screws at the throttle cable assembly to separate the two cap halves and probe the wires there.
If not repairable, rather than buy the expensive OEM grips, perhaps buy an aftermarket set of the right length (and similar resistance). Most likely they will work with the OEM controller.
The other option is to get heating elements you wrap on the handlebar and install a non-heated grip over it.
