Anyone out there with this issue? My faithful heated cup holders stopped working. I have a 2017 GLE43. I replaced the fuse, it's a 7.5 amp fuse under the rear passenger seat. No help. What happens is, the red light stays on for a few moments, then times out. No heat. However, I do believe the cooling feature is working, the blue light stays on and I hear the cooling fan engage. So what can be the problem?
