ANCIENT ~ Welcome to CACC ...and great choice in color, too.
You'll probably have an answer soon.
Had to replace my flasher earlier this spring before our cross-country run to BG, and this Chiltons manual I had was a joke...it had me going thru the glove box to get to the fuse panel :confused ...didn't sound right so I bailed and went to the chevy dealer down from my office and let them do it. Still not sure where the fuse panel is exactly, but I don't worry about it now.
Good Luck !!
