Didn't the 735i have a different system you could install on the 535i and have all windows roll down at once or something?
Alright, so I have an '89 535i and i am tired of waiting for the front windows to roll down before i can roll down the back ones. Anyone have a way to install a switch that will simultaneously roll down all four windows at the same time? Any advice will help. Thanks!

Not possible all 4 simultaneuosly. Max. Amp the GM will allow is 35 A as far as I remmeber, then it will trigger and stop all.
Try by yourselves
An alternative is you rig up aftermarket alarm system window module to your car.
Roll the back ones down first.

I put a newer GM in my car so all my windows would be one touch, and can get 2 to go down at the same time. Any more than that and they all stop.
