The power windows in my car move very very slow aside from changing the motors is there any thing I can oil or grease to help them move faster?

 

WELCOME ABOARD, THE 84 THUR MID- '86 HAD THESE CHEESEY PLASTIC RIBBON DRIVEN REGULATORS. BEST TO REPLACE THEM W/ THE LATE '86-96 GEAR DRIVEN REGULATORS. I BOUGHT MINE FROM CORVTTERECYCLING, WHICH WERE AC DELCO AND ARE FASTER AND NOT **** TO BREAKING AND ARE NOT TOO HARD TO INSTALL.
