My car is a91 ef hatch base model and the brake lights and gauge cluster lights don't work. I replaced the fuses four times and it blows immediatly. I'm guessing there is a short but I don't know what to do about it. I unplugged the battery terminal to put on the power wire to my sub and tightens everything back to normal. If any one has any advice let me know thanks.

 

start looking for grounded wires.

 

Ok today I'm checking all the wires and trying to find something

 

Chances are you have water in one of your bulbs.
Start by replacing all the lamp bulbs first.

I had the same problem in my wagon, and it was a soaked bulb socket.

 

grounds are a good start, but a better start will be a multimeter.

 

The wires look good. And to use the multimeter do I just cut the wire and test it?

 

there this tool that looks like an ice pick with a light inside call a circuit tester. It will check if the wire has power to it and therefore if it is grounded




looks like that

 

or use T-pins and probe with meter if need so but better to use meter only and no cutting.

 

I have this same problem in my 91 DX.... all lights work except brake ligts...
keeps blowing the 10 amp fuze under the hood .... also knows as the horn fuse...
any tips?
already replaced the brake light bulbs and i even have put 30 amp fuse in...
