SLOW POWER WINDOWS
 

I have a 2002 SIlverado EXT Cab and the POwer windows are soooooo slow, the driver side is worse. I have replaced the motors and complete assemblies in both sides with both OE and aftermarket, with only temporary and moderate improvement. If it is cold out they sometimes barely move. ON the advice of my local glass guy I LOADED up all the moving areas with silicone, this did NOTHING. Why does Ford have windows that will take off a arm if not careful and GM's barely move? Any suggestions?

I have the same problem on my 99'. I have no idea on how to fix this. My drivers side is extremely slow but the passenger side is "normal" speed for a GM. Does your drivers side "clunk" when you roll it all the way down? Like its going to go through the bottom of the door or something?

I have the same problem with my 05. I would guess it has something to do with the colder weather. During the summer I don't notice any differance at all. It could also have to do with the load on the vehicle. Are your lights on, playing the radio, trying to get all the windows down at the same time? Things like this could be a factor.

I am no thaving the issues ya'll are, but I know that the electical system seems to be a little short on power. If just idleing, lights on, and i roll a window down the lights dim a little. I don't know if the wires are too small or the alternator doesn't put out enough. I don't know if this info helps, but I figured it can't hurt.
