last year i cleaned contacts in switch,worked for a while.this year,not working again.wonder if anybody has part numbers for replacement as i would rather replace parts than try cleaning again.

 

Trust me, you would rather try cleaning again.
If you want a new one your shelling out over $400.

If you can find some one though, they usually sell them for cheap. The problem is that eventually that one will go bad too. I think mazda is running far too much current through that switch. Maybe you can come up with some kind of custom relay set up.
