I have a 2001 IS300. My Tail fuse keeps blowing out and everytime I put in a new fuse and turn the lights on it blows it again. What could be the problem? Has anyone here had that problem? My headlights, brake lights, And dash lights work fine. Its just my running lights that keeps going out. Could it be a bad relay? I need help, I can't drive at night because i have no light in the back. Thanks in advance for any help.

 

There are obviously some crossed wires somewhere. Have you recently been messing with the wires? Or have you had a lighted spoiler installed? Something may have been crossed or grounded improperly.

 

have you changed your bulbs recently?

 

I found what was wrong with my lights, It was the taillight wires that run underneath, right above where the muffler is located. It was melting the wires together which made the fuse to blow everytime. Thanks for the replies.

 

No problem! I knew it had to be something with the wires! Glad you got it figured out!
