I have a problem and need help from Auto gurus. In my 2002 venture the
both break light don't work. I have checked and replaced all the bulbs.
The strange part is that all 4 bulbs work, but when I press the break
the break light don't. I have all correct bulbs. Please suggest what to
The word is BRAKE.
I assume you mean that all four bulbs test okay. If that is true, then
use a tester, either a test light or a voltmeter, and go to the brake light
switch. Have someone press the brake pedal while you check at the switch
to see if you get voltage.
If you don't get voltage, move back from the switch toward the battery and
check for broken wires, blown fusible links, fuses, etc. It would be best
you had a schematic to help you find the failure.
If you do get voltage, then there is a bad connection or broken wire between
the brake light switch and your brake lamps. There is no simple way. You
just have to trace it out until you find it.
Well said, Mike...corroded or broken grounds are perhaps the most common
reasons for lights not to work.
My only suggestion is that the OP work systematically through the system.
He could as easily start with the ground points as with the brake light
