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. well, one way to test it out is if shorting some of the pins make a remainder in terms of the brake light situation.I have a 2003 Grand Caravan, the brake interchange went regretful, the lights stayed on at all time merely as you described.What I DO remember is that I fiddled with the erstwhile switch good like you did, and indeed, the lap would complete in a eldritch manner, however, once i cracked it exposed, it all made sense.If one of the pins gets ability when it is supposed to NEVER get baron, it trips a switch in your splashboard ( I could hear it click ) that made the bracken lights turn off permanently until I restarted the car.It ‘s very complicated to explain and I do n’t remember much, but do n’t be surprised by how the switch operates.

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.

With the Switch Open[brake pedal being pressed] you can see the two black tabs push the connection apart so they are not touching each other while the third pair of connection is left untouched and in contact with each other.

When 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.

I still couldn’t figure why the brake lights wouldn’t come on at all though. I thought I hooked everything back up, put in the correct fuses according the plastic top. Finally I decided to life the IPM(fuse box) out of its slot to look under it.
Think I found part of what the previous mechanic might have done. Too bad, right after I found this it started raining again. Had to close the hood, guess I’ll have to wait till after work tomorrow if its not raining to take another look.

I think it was working correctly and what I have shown above is how the switch is supposed to function.With the Switch Open [ brake pedal being pressed ] you can see the two black tabs push the connection apart so they are not touching each early while the third base pair of connection is left uninfluenced and in contact with each other.When you push the switch in [ let go of the bracken pedal ], the reverse happens. The two black tabs move backwards. The larger check is enough to push the two connections together, while the smaller tab is n’t enough to force the middle copulate of connections to touch.I placid could n’t figure why the brake lights would n’t come on at all though. I thought I hooked everything back improving, put in the right fuses according the fictile top. last I decided to life the IPM ( fuse box ) out of its slot to look under it.Think I found separate of what the former mechanic might have done. Too bad, veracious after I found this it started raining again. Had to close the hood, guess I ‘ll have to wait till after work tomorrow if its not raining to take another spirit.
