My 2009 Nissan Murano sit for a couple of days with a bad battery. Put in a new battery and had to get a new alternator installed, now the clock, radio, cd player and the overhead light in the front will not work. Was told by the mechanic that Nissan said to unhook the battery cables and touch them together for 5 seconds to reset the ECM......we did that and still nothing. We have checked the fuse box and did not find any blown fuses. Does anyone have any ideas?
