Hello! This is my first post so please bear with me. I have been reading this forum for awhile and am amazed by the wealth of knowledge. I am currently trying to fix the power windows in my 1984 GMC Sierra and have seen the modification for the relay system to allow my windows to open and close faster and I figured before I did that maybe someone had modified their wiring harness so that they could have the "Express-down feature" (Thats what it's called on my 2005 Impala). It is where you fully depress the window switch once and the window will go down all the way automatically. Any help would be appreciated.
