Brake light problems / 74 Charger

[skywardpc]

Banging my head on this one.  Actually hit my head so hard on the steering wheel while getting out of the floor of the car, it knocked a lens out of my glasses.  Anyway, back to the issue at hand. 

The brake lights do not work.  The fuse looks OK that handles the brake / stop lights.  In the fuse block, fuse #4 keeps blowing for some reason, not sure if it has to do with this issue or not.  I have replaced all the old nasty bulbs for the backend of the car because they were all blown too.  Not sure if the brake / stop light switch could and can go bad.  Not sure if it is a wiring thing or a switch thing.  Any ideas I can try that will help point me down the right road? 

The dome lights work, the turn signals work, head lights work.

fuse 4 ( the lower one of batt side ) is cigar lighter, glove box and parking lamps ( then also cluster lights )

the fuse that feeds the brakes, also feeds hazzards and dome ( also trunk light ).

Check if you have power at pink wire at pedal switch... If not, is that wire related. Then press it and check if you have power at white wire of turning switch harness... if not, the is brake pedal switch or white wire itself ( that white wire is a straight line from the white wire from pedal switch )

if you have power at white wire on to undercolumn turning switch harness. IT COULD BE the turning switch itself... sometimes is fixable, sometimes not, so it culd be time to get a New one. they are available but I preffer NOS pieces. If you care, there is a NOS one being sold at Moparts... CHEAP.

Relation between fuse blowing ( what is not the brakes ones ) and brakes ? if some bulb or socket ar tail lights is somekind shorted YOU CAN GET a blown fuse of course and not necesarilly the brakes one, because the bulbs and sockets are someking related between parking functionand brakes/turn/hazzards function. Is HARD that does happen but rarelly POSIBLE

That fuse cavity on my 74 melted, so in order to keep the brake lights working the previous owner did this. Ran a wire from the acc power connecter at the bottom of the fuse box to the brake light switch. I spliced in a inline fuse for now but am going to clean that cavity up and try it again. Like nacho said, that fuse also powers the trunk,dome and hazards.

I had the same problem about 2 years ago...I wound up replacing the brake switch under the colom...Oh and the floor dimmer switch too...I think they both are the same for the Dodge ram, so they were cheap...

Thanks folks.  The problem was with the switch.  Actually some corrosion had the switch working and then not working.  New switch was installed and yeah, almost street legal.

 Even if some bulb or socket ar tail lights is some kind shorted you can get a blown fuse of course and not necessarily the brakes one, because the bulbs and sockets are something related between parking functional brakes/turn/hazards function.
