1991 Honda Accord break light issues help

[jstone]

I have a 1991 Honda Accord all of the sudden I push on the breaks the 20 amp fuse blows and the horn and break lights wont work, it also wont go into gear. I keep installing fuses and they blow out. I changed out the break switch by the break peddle that did not fix the problem. Is there another reason why the fuse will be blowing when I push on the break peddle? All of the other lights work? If no one has any ideas do you know of a good trustworthy mechanic in the Tacoma University place area? This is my commuter car

I'm sure I could figure it out for you, I'm in Tacoma and could come help you out.

Sounds like you have a short to ground somewhere that's grounding out when the wire providing power to the brake lights is energozed. Check the tail light harnesses in the back and on the trunk lid. Especially where a harness would bend and flex when the trunk lid is opened and closed a break where the harness is attached near the trunk hinge is pretty common as well as a brake light bulb socket melting and allowing the pins to touch and short out. Usually happens when wrong wattage bulba are used. Also a short in a relay can do the same.

like above, truck lid harness and also- my Civic's problem was rust in the trunk lid. The light sockets themselves were all rusted and blowing bulbs. The lights were leaking too.

Fix? Take a torch to a nail, get it red hot and burn it through the lowest part of the interior light housing so it drains any water. Done this with a headlight on two old nissans before too. Heat from the lamp will usually keep it dry and not fogged.

I just had my F-350 start having dash lights popping on, door bell rings, window switches started working intermittently then, stopped working all together. Stopped by a friends shop and he yanked open the harness right at the door to the body. Two wires just split clean in half. Crimped them together and all the problems solved. It was strange so much was connected to one ground wire in a door harness.

The fact that it wont go into gear makes me think its the sensor on the brake pedal itself.  That would also explain the lights not coming on, but not the fuse blowing.

typically most shorts are in the rear shorted socket or add on trailer plug in . on a 1991 Honda they have a transmission control unit that looks for a signal from the stop lamp switch so if something on the stop lamp side is shorted the controller wont see the signal. the cruise control gets a signal from the lamp switch aswell . but first i'd snoop around the rear lamps , pull bulbs and look for a short , I've seen wrong bulbs short out in a socket too .

so the under hood fuse # 25 is the one blowing I assume . , doe's it blow when you replace it right away or only after steping on the brake switch ? the shift inter lock unit is feed by it aswell . by chance have you spilt any thing in the shifter , you may want to pop the cover and make sure the solenoid isn't shorted , after you have checked in the rear .

Yes its fuse #25 and it pops when I step on the break peddle. Sometimes it will let me shift once then I will put it in park then I can't shift back out of park, then some times it just pops I have changed out the lights I will check for a bad wire

Thanks for all of your responses

more than likely in the rear ,
