Tail light fuse keeps blowing

start inspection wiring for chaffed or cut, or pinched wiring. no one can tell you where the fault lies without being there.

Look for shorts in the circuitry.

have a look at the fuse. If its all black and you see small bits inside you have a dead short in the circuit. Check the wiring for any metal to wire contact, especially at any points where wires touch any metal. If its just melted in the middle but did not blow violently its overloads the circuit is drawing too much current for too long, look for fused contact or stuck relay etc.

check wiring on shift columb going to turn signal switch it could be the switch it self I had this happen on a new chevy truck hope this helps good luck jerry

unplug the tail lights then replace the fuse if it doesn't blow the fuse plug one ail light in at a time

you got a wiring issue that keeps shorting out fuses find that and that should take care of everything else

dead short in wiring- either a trailer plug?? or did you have a amp/subwoofer installed- or possibly something large in trunk smashed wirng

try the fuses

you have a short somewhere, unplug the tail lamps one at a time and see if the fuse still blows. if you disconnect one and the fuse does not blow and everything else works, the problem is in the tail light assembly. if not, the short is most likely in the wiring harness which can be a bit tricky to diagnose. alldata.com/diy offers one year subscriptions to cars with all the repair info and they have excellent wiring schematics. dont forget to try the front marker lamps in addition to the tail lamps.

My blinkers and brake lights work but my tail lights won't come on.
