Relay constantly tripping?!

[irishluck]

There is a relay or switch under my dash area (imagine the radio, go straight down to the floor, there is a relay behind the dash right above the floor)

I know it has something to do with my braking system. I just want to get the right part the first time ti fix it.

Every time I'm driving or flip the key on, this relay trips about a couple 1000 times a minute. When i hit the brake, it stops.

So is this a bad brake switch or a bad brake relay?

Id post a sound clip, i have one, but it wont let me post it on here.

Turn signal switch is the most likely cause

Even though my turn signal isn't on or anything and the turn signals work fine?


I mean it stops tripping when i hit the brake, that can be the turn signal switch?

Does the noise stop when the turn signals are on too?

What can happen is, the Flasher sw at the top of the column gets crud in it because it faces Up. That crud causes a bad contact that won't allow sufficient current to hold the relay's coil where it's supposed to so, it "buzzes" (if that's your problem). They will still work fine because using them supplies a better ground for the relay to use.

Try the Hazard SW On/Off a few times and see if it doesn't clear it up (temporarily). If it does, you can either take the sw apart and clean it (not easy if you're not into doing that kind of stuff, lots of plastic tabs and springs inside) OR replace it. I cleaned mine a few years back and it hasn't come back

If it's Not associated with the Hazards or Turn Signals it is probably still a bad contact or connector causing low current to that coil.

No, the turn signals dont stop it or anything. Its just the brake that does it. Now just in case i didn't explain the relay enough.
Its straight under the radio area about 3 inches above the floor.

But no the turn signals do not stop the relay tripping

sounds like your hearing the flasher relay. your describing the flashers location

[irishluck]

Even though my blinkers have nothing to play into this? My brake pedal plays into this andkeeps switching it on and off not the blinkers. Would it still be that?

[irishluck]

So i guess you were right, it is the flasher relay that is making that noise, what could be causing this issue though
