Window?

[sareljr]

On my 05 2500hd's passenger door, when I roll the window up it goes about half way with no problem but then slows down quite a bit till it reaches the top, but when I roll it down it doesn't have any hiccups, is this due to a bad motor, or do I need a new window regulator?

Just replace the complete regulator and motor assembly. I had the same issue with a Bonneville I use to own. No issue after everything was replaced.
