Looking to replace this part. The window "sticks" as it gets close to full closing and the gears seam to skip.

Hi there! I am very sorry for the long wait; we appreciate your patience during an incredibly busy season.

Take a look at the 39-032 and 39-156. The important difference between these operators is the length of the link arm. Review our specifications and compare them with yours to confirm which is the best match.
