The previous owners mechanic did something to disable the brake lights all together to stop battery drain, I'm just trying to figure out what he didOne is the ECM tester,and the other is for other power ascesorys,no they should not be plugged in to any thing.

Well, one way to test it out is if shorting some of the pins make a difference in terms of the brake light situation.

Check the fuse box...it could be that he just pulled a fuse.

So I also cracked open the old switch. I think it was working correctly and what I have shown above is how the switch is supposed to function.alkizmo wrote: ↑Jun 14th, 2015 5:08 pmWell, one way to test it out is if shorting some of the pins make a difference in terms of the brake light situation.
I have a 2003 Grand Caravan, the brake switch went bad, the lights stayed on at all time just as you described.
What I DO remember is that I fiddled with the old switch just like you did, and indeed, the circuit would complete in a weird way, however, once i cracked it open, it all made sense.
If one of the pins gets power when it is supposed to NEVER get power, it trips a switch in your dashboard (I could hear it click) that made the brake lights turn off permanently until I restarted the car.
It's really complicated to explain and I don't remember much, but don't be surprised by how the switch operates.
Follow the instructions that came with the new switch to a T, study it before you go play around with it. There is no turning back once it is installed.

Thanks, the previous mechanic has certainly done something funky in the fuse box.

There are multiple pins, but if the incorrect pins get power when they never should, it trips something inside the car that locks the brake lights on or off, I forget, I just know it worked weird like that.Evil Baby wrote: ↑Jun 14th, 2015 11:15 pmWhen you push the switch in[let go of the brake pedal], the opposite happens. The two black tabs move backwards. The larger tab is enough to push the two connections together, while the smaller tab isn't enough to force the middle pair of connections to touch.
