Well you narrowed it down to an electrical problem, get yourself a dmm and start chasing wires.
I've also seen a bulb burn out and short causing the fuse to blow when the brake pedal is depressed. double check your fuse again and if its still good have at it with the digital multimeter.
how do you change a brake light bulb from a citroen c4 tail light unit. thanks
Waht is location of BMW x5 brake light bulb to change?
The brake light bald can be accessed through the trunk of the car. Remove the rear tail light cover to access the brake light bulb.
Look in the trunk, there is cover for the brake light, remove and you will have access to change the bulb.
You have to take the whole light out, there is two screws to take out, then the light will pull out. Then change the bulb. Greeny
Just unscrew the rear brake light, turn out the socket, and replace the bulb.
There are three black caps that screw off in the trunk behind the brake light itself unscrew them and the assembly comes out then change bulb
change the light bulb,
In order to change the brake light, check your manual for directions. You will need to remove the cover and replace the burnt out bulb.
how to change the rear tail light bulb on a 2004 Nissan maxima
If you can't get to the back of the light through the trunk, you have to remove the light to change the bulb from the rear.
Have you checked your bulbs ? The tail light / brake light bulb has 2 wires inside it In my case I have had to change each bulb because the brake light portion did not work but the tail light portion of the bulb did ( I'm assuming that your front park lights are working )
