Hi hockeyturk,
Sluggish door glass movements are usually caused by bad runchannels. Either they have hardened over time or the rubberised lubrications are worn off.
You can try spraying some silicone spray or any other rubber revitalising products to make them work better or replace the runchannels which would be a longer term remedy.
