    Recently I had to install a new driver's side power window switch for my 86 K5, and if I hold the switch up (to roll up driver's side window) the power in my truck seems to decrease. My radio and headlights dim, and my ac,heater slacks off. Is it the switch or wiring througout my blazer???

    How was everything before the switch had to be replaced? It's been my experience that power windows suck the life out of electric's when they are rolling up anyway but, it may be possible, that it might be the wrong switch and when it's on its up it may be grounding, or you window motor gears/ window tracks are dry and it's really taking the power to push the window up, because the track and such is dry and not wanting to move freely. Hope this helps.
