As a new Chevy truck owner, I'm posting for the first time. My truck is a 1995 Suburban 2wd. As a Georgia truck in Chicago, it's a rare find. My first question regards a power mirror issue. When the switch is selected for the driver's side, the D side mirror won't go up. When the switch is rotated to the passenger's side, the P side won't go down. Is this a switch problem or is there an issue with each mirror assembly? Thanks for the help!
