1994 Yukon Driver seat motor slow moving

[Stutz6]

Ive noticed my seat has slowed considerably and does anyone on this site sell new or used ones?
Also I do not know if I can replace the motor itself or is it part of the track and all? Thanks

I have a full motor assembly in the garage out of my 99, I also have the controls and lumber pump. It all worked 100% when I removed it last month.

If interested let me know
