Hi all, I have a 2005 M7 and when I turn on the left hand warmer on low the headlights and gauge cluster die and loose all power but the sled still runs. The high setting and the right warmer seem to work fine, (not sure if they get hot, I just got the sled). I used an ohm meter on the warmer element and the switch but I'm not sure what is causing the problem. Is there a certain ohm reading I should get for each? Any input would be appreciated. Thanks for reading.
