QUOTE: Originally posted by lionelsoni Can you tell whether the buzzing is from the e-unit or the motor? Does it stop if you shut off the e-unit?
QUOTE: Originally posted by jerrylovestrains Then it is the E-unit that is buzzing. I worked on a 2025 once, and the brush's wires come off of the E-unit lug pretty easily. Or, the brushes themselves might be shot, its cheap and easy too replace them.
QUOTE: Originally posted by lionelsoni Adam, you should try to bypass the e-unit as I described to be sure it's the culprit before going to the trouble to replace or repair it. (Do you understand that the buzzing is normal?)
