Manual windows change for power windows

Hey guys, real quick. I purchased another DA (my 5th) just recently and noticed that it has roll up windows. I am outside right now trying to convert over to power windows with my other DA’s doors. The problem is, I cannot seem to operate the windows. I checked all the plugs, fuses in the correct (20)fuse locations, started the car, but still no operation. I end up putting the door back on the other DA to see maybe the motor went out or something, and that turned out not to be the case.
What am I doing wrong, and is there a relay for the windows/where is it located? I’ve been pampered with power windows with all my DA’s and don’t feel like cranking up windows now. Please HELP! Thanks in advance.:stare:
