Weird fuse issue
Hello, I’m having a strange problem with my reverse lights, fuse.
Now I know C5 guru’s are going to say the reverse lights only have a relay, and you are right. Engine bay reverse relay is fine and working properly. The interior fuse box has a fuse for the brake-transmission shift interlock, #21. It keeps blowing a fuse only when I shift into reverse and my reverse lights don’t work. I have a manual transmission, and just discovered this while putting in a back up camera and Joying radio system.
I have suspected my reverse lights have been out for some time, since I never saw any white glow when close to the garage or anything else late at night when reversing. I just never drive her enough to care. So that is why I do not think it was any electrical handy work in this project that is cashiering this either.
I tested the relay, it works; I swapped the fuse with a slightly larger one, just to check, and it blew that as well. Wondering if anyone has had this happen before and possible what may be the problem?
Thanks for the help!
