I recently had a local audio shop trouble shoot a few minor issues with a back door speaker and 3rd row subwoofer wiring issue. Plan was speaker replaced and new wire run back to the sub- easy stuff.
When I picked it up, the Viper security fob didn't work so the tech realized it and solved it quickly with some "wiring" fix.
All seemed fine but I was made aware by someone driving behind me that I had no brake or tail lights. I also noticed when I pushed the Viper button to lock the doors, all normal lights blinked except the rear taillights. So I figured it has to be related to the work done at the shop. I took it back yesterday, they checked all of their work to make sure nothing was unusual and they checked voltage to the rear lights and found no reading. The top of tailgate brake/running light works normally and both blinkers work fine.
Shop wants to keep it until their more "experienced tech" can trouble shoot it tomorrow so maybe he will discover the gremlin, but so far they think its unrelated to any work they performed and maybe they are right...
Question is what are the typical reasons both tail and brakes lights might go out at the same time when fuses are all checked as good? A previous owner has converted most all bulbs to LED and I hear those can create weird problems but all bulbs work when I tested them in working sockets (rear blinkers worked so plugged all bulbs into that and worked fine).
Any advice is appreciated.
PS- I'm new to the site so forgive me if I'm not fully versed in how this all works but really love having some experts to advise me (at least way more expert than me!)
