Vehicle make/model = olds alero
Year = alero
Mileage = 87,210
Engine size = 4 cyl
dash lights = Service Vehicle Soon
codes = No
tech = JK
question = The left and right brake lights don't work but the middle
brake light does. There doesn't appear to be any blown bulbs or fuses.
JK:
The high mount stop lamp is on a different circuit than the lf. and rt. brake lamp as it come out of
the lf. fuse dash fuse/junction block. It is possible that you have a bad connection within or on the
back side of that block for the wires that run to the lf. and rt. brake lamps. Since you did not leave
the model year, i went with a 2001 alero. These blocks have a tendency to get corroded by water
intrusion. It may show signs of water intrusion by removing several fuses and look for signs of dried
up water/rust, also on the back side of teh block where all the wiers come out. This condition is
probably the reason for the service vehicle light on the dash. but cant be sure unless have the
BCM (Body Control Module scanned for codes.
