PW windows have same problems as manual plus motor problems...
"standard" lubriplate is white grease in most cases.
Fiero window rollers center can bind on the pivots and won't roll and most lubes just make more problems because Most oil/grease will attack most plastics.
Lube them only helps for a short term then often is worse soon after.
Some have better using new rollers by removing new pivots then push on the old pivots.
Check

If the big spring is binding then you have a hard time working the window... "Clean" spring to get out rust and dirt w/ cheap spray oil then lube w/ silicon or Teflon. Careful use of a screwdriver to separate coils to clean.
