I have a 4th Gen Prelude and I was wondering, what would it take to get the passenger side window to auto roll down like the driver's side? Could you simply get another "auto" switch and replace it with the non-auto switch? Would this require getting the same exact part number?

 

It's something in the motor istelf (or the motor circuitry) that lets you use the auto-down switch. The driver side window motor has a three wire plug, whereas the passenger motor has 2. You can't just use the Auto- switch. I took them apart and swapped motors on my regulators for my RHD swap, that's the only reason I know this... hehehe
