well i had the same problem. my passenger side window would just about stop. it now runs basically the same speed as the driver side. yall must remember, these trucks are old and dont have the tech as the newer ones , so they are not going to run as fast. but here is the kicker. my dad had a F@&D (85) and the windows were real fast, im mean fast. i wish mine went that fast. oh well i guess they need something good on those trucks huh
