Just buy a new regulator, yours is broken.
New one should not be in multiple pieces. http://www.hondaautomotiveparts.com/...y5=DOOR+WINDOW
Carefully examine the run channel rubber for deforming, and you might take the opportunity to clean the rubber with hot soapy water. Dirt in that rubber strip makes the glass hard to roll up.
A good dose of spray silicone lube into the run channel rubber on a regular basis can help too.
If you really want, that big spring has to be positioned/wound to hold up the weight of the glass when it is all put together.
Once the glass is detached and the 2 gears don't mesh, that spring can snap the regulator to the fully raised position, and attempt to chop all of your digits OFF if you don't keep them pulled out of the way.
