Hello I've got a quick question my onstar on my 07 Yukon has no light on...the temperature is off I push the buttons and nothing is on...like the whole mirror has no power...could it be a fuse
It doesn't appear to have it's own fuse. Do you notice anything else not working? It may be combined with another fuse/circuit. Also there may be a plug or connector at the top of the windshield that you should check as well.
Thanks and yes my dash lights were on but nothing worked as well...I replaced fuse 45 and 46 and they started working...but my mirror never came back on
