Exterior Rearview Mirror problems of the 2004 GMC Sierra

While driving the sideview mirror folds inward . The owner's manual stated that this was a normal procedure.

The right side power extending camper style mirrors on my 2004 GMC Sierra 2500hd pickup truck has blind spots that will not allow you to see cars on the right side of the truck. You either adjust the mirror out and pointing down to see cars on the right side or you point the mirror towards the rear of the truck to see the back corner of the truck to back up to things. But you can not see both at once.

Consumer had difficulty seeing while driving due to a blind spot when it was in reverse. Passenger's side mirror had trouble telescoping to the back.
