Dash lights, tail lights, brake lights, not working 1965 mustang

Does the fuse blow before or after you step on the brake? If it blows only after you step on the brake, and voltage from stop lamp switch only goes to rear brakes and not through multifunction switch. If only one connector at the rear for brake lamps, take connector loose, step on the brake, if the fuse still blows, the problem is before the connector. You could Use new wire from brake switch feed, when brake switch is activated, to the rear brakes. Leave pigtail at both ends, splice in new wire, You could let new wire just lay on the ground, for testing, from brake switch to rear brakes. If the brakes work and doesn't blow the fuse, Make the new wire permanent and route the wire properly. Just my opinion. I don't have wiring diagram for your model year.

Turn signal tail lights and BRAKE LIGHTS NOT WORKING

It can be faulty brake light switch causing the problem or its blown brake light bulb. First check and confirm brake light lamp is working and that's not the case.

For turn signal not working it can be faulty turn signal switch or its issue with wiring:----

These will help.

Thanks.

Which light?
One light not working? Check the bulb.
Both tail lights not working? Check the fuses and the bulbs.
Brake light (or lights) not working? Check the bulb, fuses and brake light switch.
Totally no lights in one or both tail light assemblies? Check the plugs on the light assemblies from inside the car. Check the fuses. Check the grounds (might be some under the dash for those lights).

Could be a double fillerment bulb, replace it . Second option replace fuse. If that does not work and the parking lights, some dash lights dont work also it could be the worst option. the headlight switch. difficult to access behind the dash.

The odds are the one fuse is blown for the dash and the tail lights. And the wrong bulb may have been put in for the brake light. The brake light is feeding back into the tail light circuit causing the fuse to blown out.

Change out the bulbs with OEM bulbs and replace the blown fuse. That should fix the problem.

Bulbs work just like a fuse. When old they just short out like a weak fuse bowing out. Since the lights do not have a fuse you need to replace the headlamp switch for this switch controls the tail lamps. The directionals are controlled by the directional switch, and the brakes are controlled by a brake light switch. Those have fuses for they have switches. Headlight switches do not have a fuse

Fuse panel is under the dash also as I have found with my own graceful daughter, there is a brake light switch that connects to the brake pedal itself. It is hard to get to and even harder to see but a lot of times these switches get bumped and they can not make connection when the brake pedal is depressed. Hope this helps

Hi.

Test with a voltmeter the contacts to the fuses for tail lights and brake lights. If there is no power getting to fuses from instrument panel, and switches had already been replaced, then it is a wiring problem from switch to fuse box, otherwise from fuse box to lights. the defective wiring must be repaired or rebuilt.
Regards.

Are the rear bulbs OK?
Is the ground good at the rear?are the sockets good?
Are there tail lights and a license plate light?then the ground is OK.
All the things that you say do not work go through the signal light switch....it may need replacing.
First make sure the bulbs and fuses are OK and power is getting to the signal light switch and to the brake light switch.
Nice car!

it might be a problem with the electrical circuit. first of all check your light bulb,replace it if fused. else go for the spring check attached with the brake pedal n atlast the wire connection check. Hope it works..:))
