pressure switch just in front of the master cylinder they crap out sometimes.Nice 64 galaxie you're at about the same stage as me,wheels and other little bits and pieces

 

use your test light, start at the back, are you getting juice to the socket? follow the wires forward to see where you lose juice. do you have juice into the switch?

 

To quickly test the pressure switch pull the terminals off and touch them together ,if your brake lights come on then that's your problem.and keep them connected while testing makes it easier especially if your'e doing it by yourself .If you have power going to the pressure switch then one of those terminals will have power full time .If not it's before the switch probably under dash ....Good luck

 

Nice that's easy enough ill try it an let you know how it goes

If the rear turns work, it's almost sure that it's the brake light switch. The only other possibilities are that you've lost power to the brake light switch, or that power from the switch isn't making it to/through the turn switch.

 

Don't need to take wires off hydraulic brake switch to test. Just jumper the two terminals together and see if brake lights work. If they do, bad switch, if not, then check for power at the switch with test light. If power, then turn signal switch is acting up.

 

I used a jumper wire and the lights worked replace the switch and I got light Again thanks guys
