Weird Tachometer and Cruise Control Problem [93 Civic]

Car is 1993 Honda Civic LX, 5spd, 1.5L

1.Well this might be weird ass hell but…Well while driving today the tachometer stop working…so when i stopped to part it for the night and pull my ebrake up it worked…

As soon at the brake light goes on the cluster the tachomter works…as soon as it goes off it stop working…what can be the deal?

im assuming its the cluster?

what do you think?

  1. The cruise control doesnt work at alll…the button on the dash works…but it wont set. I have tried two different cruise switches.
    The light on the cluster doesnt light up at all…

Does the cruise control have a seperate fuse?

do the horns work? Sounds like the cluster is bad but if the horns do not work, fix them first, then the cruise should work. If they do work, you have additional problems somewhere else

yes the horns works.

More test has been done with the tachometer…
it seems like either the seatbelt or the brake light needs to be on to work…or it only works in 3rd+ gears. it totally doesnt respond in 1st or 2nd gear…do you think its the vss sensor?

i think it may be the cluster itself. If its not the cluster itself maybe a grounding issue?

now the tach works…weird shit…im thinking a bad ground some where. i got to look into any chance u know where the common ground for these lights are?
