hey so ive been restoring a car i bought this summer its a 81 gs 12a the tailights work but when i press on the brake the lights dont get brighter. my horn doesnt work and the signals light up with the running lights but they dont flash when i try and signal or use the hazards. when using the signal or hazard lights it doesnt light up on the dash or make a blinking noise. if anyone has a had this problem i would greatly appreciate any input on how to fix this thanks

 

I'm not sure about the turn signals and hazard lights but the reason your brake lights and horn don't work is probably because the fuse labeled HORN is blown. Check the fuse box by the driver's kick panel. I had this happen to me last weekend. Lol.

 

Double check all your wiring on the drivers side fender in the engine bay too. This is where the wiring for the lights are at. Earlier this week i could get my headlights to pop up and turn on, but no other lights would come on, ignition was dead etc. turned out to just be some loose links.

 

the links are ok in the fender i can get the signals to light up when i use the running lights but i cant get them to flash i also got the horn working today havent checked the brake lights yet but the signals still dont work
