What do they have it labeled for the fuse for brake lights for the vehicle above
During stoplamp operation, power is supplied from the STOP LP fuse in the underhood fuse block through CKT 1540 (ORN) to the TCC/stop lamp switch. When the brake is depressed, the contacts of the TCC/stop lamp switch close, routing power to CKT 17 (WHT). CKT 17 supplies power to both the VECHMSL fuse and the stop switch contact of the hazard switch. From the VECHMSL fuse, current flows through CKT 1320 (LT BLU) to the high mount stoplamp and high mount stoplamp resistor. The ground is provided by G450 through CKT 1350 (BLK). From the stop switch contacts of the hazard switch, current flows through the turn signal switch to CKT 1418 (YEL/BLK) and CKT 1419 (DK GRN/WHT). CKT 1418 (YEL/BLK) supplies power to the LT TRN (rear) fuse (which feeds the LH rear park and turn signal lamp terminal A) through CKT 618 (YEL). Ground is provided by CKT 1350 (BLK) to G450. CKT 1419 (GRN/WHT) supplies power to the RT TRN (rear) fuse (which feeds the RH rear park and turn signal lamp terminal A) through CKT 619 (DK GRN). Ground is provided by CKT 1350 (BLK) to G450. When the left or right turn signal is turned ON, the appropriate turn signal will flash. The opposite side will remain ON in order to serve as a stoplamp when the brakes are applied.

i would chk. break light switch. should be under dash above break pedel arm. emergency flashers will be on its own fuse, turn signals should have own fuse. as far as interior lights surging that could be ground or alt. chk. battery cables make sure clean and tight. not good idea unhooking bat. cable when running, one spark or surge to computer could burn up computer. besides that realy won't tell you anything if a diod is bad in alt. it may not show up until you tax the system. its best to take it someware like autozone, or any major auto parts store and have it chk.

Check the brake light switch under the dash where your break peddle arm rest against when it's not pushed down. Also there is a relay in the glove box, you'll see a panel in the glove box that say relays.
There are three relays in there, one for the A/C , the fuel pump and brake light. I believe the fuel pump is the middle, i can not remember which side is the brake light relay is but if you turn on the a/c while the engine is running you may hear and feel which relay is the a/c when the compressor kicks in.
Good luck and keep me posted.
SOURCE: Main brake lights not working, third light works,
Most likley the brake light switch. It has 2 different sides. One for the third brake light and one for the lower brake lights. It is inexpensive and can be changed easily. Good Luck
SOURCE: ABS light is on, brake pedal makes noise
sounds like the r/f wheel brg needs replacing when you are coming to a stop and you hear the pedal making noise does it pull slightley to the left this would conferm the r/f is the problem

Hi Renee, I have experience with faulty brake lights on these. Does only the 2 rear brake lights not work, or does the one up top in the center work?
