Well, after getting alternator replacement from dealership, memory setting was erased. Didn't think much of it since only I drive murano most of the time. Today, my brother came to visit, but I've told him his setting was erased, so that's when I've found the problem. On driver side mirror control wouldn't work at all, but on passenger side mirror- only left to right works not up and down. Does anyone have similar problem? if so how can I fix the problem without taking the murano back to dealership... Thanks oh btw its 2004 model
