Brakes have failed, mech cant help

Like i posted above the relay battery feed needs to be checked. The insulation peeling back is classic heat and most likely the cause. Check the system carefully from the fuse link to the relay in and out. If you do not have battery you found the problem.

So the grey wire I found near the windshield wiper motor didnt have a yellow strip to it that I could see. Well I dug around more and I can't find a 4 wire connector anywhere that has the GY/Y stripe... I looked near the wiper fluid and the power steering and I found the GY/Y wire by its self. It connects and turns into a blue wire. I'll keep digging around looking for that 4 pin connector.

Okay, i'll look through my manual and see where the relay battery feed is and start checking that out.

Alright so that blue wire goes to fuse E then turn back into GY/Y. I also found the 4 wire plug down below the wiper motor. I am wrestling to get it unplugged now.

The BLUE wire is the fuse link. When it blows, the wire inside it breaks. Try stretching it. If the wire is broke it willl stretch.

So the fuse link ink (It is blue) looks fine. On the 4 pin connector, the GY/Y wire has 12v going to it so its fine.

Voltage at thr 4 wire connector says the fuse link is good.
Does the wire at the 4 wire connector look ok? Not burned.
The only thing between the 4 wire connector and the relay socket is wire.
Plug the 4 wire connector back together again and check for voltage at the relay socket again.(the bare wire)

OKay, I will do that now. Thanks again for your help. I really appreciate it.

So after connecting the 4 pin socket in. the bare wire at the relay has 12v volts... I am very confused. I didn't fix anything, and now that has power.

So I plugged everything back in, I started up my car. The brake pedal is still stiff. However when I turned it off and putt the car to RUN, I could hear the brake motor buzzing.

So my brake pedal softened up and my brakes work great now! I am unsure to be happy because it works are nervous without fixing anything, it could just stop working again....

NOPE You fixes a classic issue DIRTY CONTACTS. I would remove the plug hard wire solder it and shrink tubing. Basically you cleaned the connector when you separated it and reconnected it. That plug is sketchy and needs to be repaired. Bare wires means HEAT and that should have immediately sent you there as the trouble. Good job :hick::hick::hick:

Better check the connections on the plugs. Bet they are corroded and burnt. You will have to address that connection as explained above. That connection is FAULTY!!
