1 switch for 2 windows?

[J-440]

Am wanting to use my power window switch to roll up/down my 1/4 windows at the same time. I'm using Electric Life's BMW switch kit. The switch has 6 terminals. I've hooked the switch up correctly and have just spliced and wired the motor wires to the same terminals. Obviously this won't work because both windows will only move 1/2" and they both stop. Is there a relay or some kind of item I need that will go between the motors and the switch to send more "juice" to raise the windows at the same time? My wiring skills aren't that great so I'll need a schematic or a very patient member on this board to walk me through this. Or if someone's already done this, show me his/her website. Thanks again.

Does your switch wiring work with just one window?

Yes.

I don't see why that doesn't work then.

Is it tripping a breaker?

All fuses are good. Don't think this switch was designed to handle 2 motors. Only had room on my center console for 3 switches. Figured I'd run it this way. Do they make a relay or whatever to give this window switch some extra "oomph"?

Several ways to do this. Relays or window module. The DEI 535T will also let you do one touch up or down and it will work with positive or negative triggers. One module controls two windows up and down or 4 windows one way only.
