Narrative:
On radar vectors, expecting mall visual runway 34L at seatac, in turn from 160 degree heading to 270 degrees, controller gave us mall visual runway 34R. Asked if we had airport or mall in sight, could not see airport, had mall in sight. I was working on FMC to change runways. We went through localizer for runway 34R. There was an aircraft behind us for runway 34L. There was no conflict with other aircraft. Captain corrected back and intercepted the localizer. The minimums for mall visual are 3100 ft ceiling, 7 mi visibility. We were going to ask for the ILS approach, when controller changed runways. Approach/landing normal. The problem is approach control was using a visual approach below the visual conditions, and did not give us a lot of time to change the approach in the FMC.

Title: A B757-200 FLC OVERSHOOTS THE LOC COURSE FOR RWY 34R AFTER A LAST MIN RWY CHANGE FROM RWY 34L BY APCH CTLR AT SEA, WA.
Narrative: ON RADAR VECTORS, EXPECTING MALL VISUAL RWY 34L AT SEATAC, IN TURN FROM 160 DEG HDG TO 270 DEGS, CTLR GAVE US MALL VISUAL RWY 34R. ASKED IF WE HAD ARPT OR MALL IN SIGHT, COULD NOT SEE ARPT, HAD MALL IN SIGHT. I WAS WORKING ON FMC TO CHANGE RWYS. WE WENT THROUGH LOC FOR RWY 34R. THERE WAS AN ACFT BEHIND US FOR RWY 34L. THERE WAS NO CONFLICT WITH OTHER ACFT. CAPT CORRECTED BACK AND INTERCEPTED THE LOC. THE MINIMUMS FOR MALL VISUAL ARE 3100 FT CEILING, 7 MI VISIBILITY. WE WERE GOING TO ASK FOR THE ILS APCH, WHEN CTLR CHANGED RWYS. APCH/LNDG NORMAL. THE PROB IS APCH CTL WAS USING A VISUAL APCH BELOW THE VISUAL CONDITIONS, AND DID NOT GIVE US A LOT OF TIME TO CHANGE THE APCH IN THE FMC.
