I need help!

My mazda 6 had a broken passenger side window switch on the master switch ( drivers side). This was replaced with a second hand one. have changed both drivers and passenger side power motor, plus replaced the master switch. the windows stil dont work and the normal reset procedure for the windows doesnt work, as the windows dont go down

 

Definitely the most bizarre issue I've ever heard but plausible if replacement part is wired incorrectly or not a match for your car.
Here is the wiring diagram, needs Flash to view it:

Are you 100% certain the 2nd hand switch is the exact part number for your vehicle? May look the same, but as mentioned above it could be wrong. I ran into a similar problem in my Nissan Primera ( Infinity G20) switch was identical, plugs identical, but it would blow fuses ( can't remember which)
