Good Morning Tim, Our shops do not have any certifications from that manufacturer to be able to work on your electrical systems. Due to this we, we would not proceed with this specific repair. Ideally the shop can provide some assistance by looking up the company contact information for you. We aren’t the right place to repair it but we can still be helpful for you if you want to contact the shop directly.

None of the Trek e-bikes have a throttle and they would likely not be allowed to work on it.
