Hi Scotty we own a 300M and the 10amp fuse that protects the interior lighting, radio, power locks and mirror keeps blowing. I plug in the diagnostic tool and it doesn't communicate with the control unit . Every time i shut it off it reset the climate control settings .

you have a live short in that system, try this video https://www.youtube.com/watch?v=pjXt7_gusgM

Thanks !

While you're at it, see if you can find an in-line fuse on that circuit. Only mentioning this b/c my fog lights stopped working a few years back. When I finally got around to tackling the "problem," I simply traced wires from lamps back to battery & discovered an inline fuse capsule whose glass fuse was blown. Cheap fix. Felt like an eedjit because I couldda fixed it years ago had I known!

Thanks !
