Both my brakelights are not working. The center lamp is working.
I have checked and replaced if needed :
1. Light bulbs
2. Fuses in both the front and rear fuse blocks
3. Circuit boards in the taillights. ( When I replaced the circuit boards, I got the brakelight to light on the drivers side in reverse only. But no backup light then. So I know that I have power to the brakelight socket)
4. I still have running lights, turn signals and backup lights when the original circuit boards are in.
Since I have the center brake light working, I don't think its the brakelight switch)
Any ideas? If its a ground, can you tell me where it is located and the easiest access. Thank you in advance.
