Good morning and welcome to JustAnswer!!
Can I get the last 8 digits of your VIN to grab a wiring diagram? Also what has been done to correct this issue?
I attached the wiring diagram..
Can you test for 12v on the Pink/Dark Blue wire pin 1 at the brake light switch? Then press the brakes and see if there is 12v on the White/Tan wire..
Keep me posted,
If the White/Tan has 12v when you press the brakes then the switch is good.. Is the 3rd brake light working?
Can you remove the 3rd brake light and tell me if the white/tan has 12v when you apply the brakes?
Ok now can you tell me if the White/Tan has 12v at the brake light switch without pressing the brakes?
Ok here is what I see... You said the 3rd brake light has 12v on the White/Tan wire without pressing the brakes and you also said that the brake light switch only has 12v on the WHite/Tan wire when it's pressed so how is the 3rd brake light getting voltage and if it has voltage why isn't it coming on? Are you sure it has 12v and ground? If so then see if the 3rd brake light is blown..
Ok if the brake light switch only sends 12v on the WHite/Tan when pressed then the brake light switch is fine.. Now have you checked the rear taillights for 12v on the WHite/Tan wire? Can you swap bulbs in the 3rd brake light and see if it lights up?
I'm sorry for the confusion but If the brake light switch is only sending out 12v on the WHite/Tan wire when press then then that same White/Tan wire goes to the junction block which is the inside fuse box and then to the 3rd and rear taillights... Now if the switch is working it should have 12v at the 3rd brake light WHite/Tan wire as well as the taillights on the same WHite/Tan wire... Can you recheck and wiggle the ground on your test light and make sure we do or do not have voltage on the 3 lights... Have you checked all the fuses on the inside and outside fuse boxes?
SInce the brake light switch is working properly then you issue is inbetween the junction block and taillights.. I would grab the test light and test all the interior fuses with the key on.. Let me know if you find any bad... The next step we will need to backprobe the junction block to see if it's recieving the 12v from the brake light switch..
I attached fuse 5 which goes to the brake light.. Did the fuse not light on both side or just one side?
Now are the fuses dead on both side or just one? If just one then replace the fuse and let me know if the brake lights work..
If you will look at the wiring diagram the White/Tan goes to Splice 311.. I attached a location for s311, can you check it and see if it has 12v?
The rear quarter panel
By looking at the picture you will need to remove the quarter panel and then locate the splice... But before you do that let's check the junction block and see if the 12v from the switch is getting to the junction block.. You will need to find the White/Tan wire in the C11 connector on the backside of the junction block.. Let me know if it has 12v when you press the brakes..
The junction block is the interior fuse box.
I Attached C11.. Its a white 11 way connector
Yes it's plugged into the back of the junction block..
Did you locate the White/Tan pin 15? And did you test when you pressed the brake pedal?
