You laugh about the fire idea. A number of years ago, I was trying to trace a lighting system short on my g.f.'s 1973 Datsun 610. It finally got me frustrated to the point of "I'll learn it, dern it". So I wrapped the fuse with foil and plugged it back in. Shortly after, a little smoke came from one of the tail light sockets. Worked like a charm, the bulb was shorting inside the socket. With today's cars and their delicate electronics, I wouldn't recommend using the "smoke signal" method.

 

oh im not going to try it. to many plastic parts these days. i did do it once in a 70 chevelle though.. god i wish they still made cars the old way

 

Mine is doing the same thing...pops instantly when I put it in reverse n can't find the problem...someone please help us haha

 

Monkeys8,

Try taking out your reverse bulbs and see if the fuse pops when you put it in reverse. Then put one bulb in at a time. When you find the side that blows the fuse, see if you can look at the wires on that side. You are looking for someplace where the wire rubbed off, got squished, broke or something that just doesn't look right. It might not be the ultimate solution, but it is a great place to start.

 

Do you have an aftermarket alarm? That could causeing issues.

 

Blows with no bulbs....

 

Then you must have a shorted out wire, between the reverse switch and the reverse light sockets, or it's the switch itself.
