I got the Roadster back from service (again) and after driving it for a few weeks the PEM is overheating. I had to limp home yesterday and it charges very slowly. I had the fan assembly replaced about 6 years ago. This is a 2010 2.0. I'm guessing that the squirrel cage fans fuse has blown, but I can't find it. I checked the fuses in the cabin and also checked the high voltage door but didn't see anything small enough to be the right fuses. Any suggestions?
