Window regulators

[RiggsLW81]

Are they interchangeable? Or side specific? Need to replace the one on the rear driver side of my DD, a 02 Caddy Seville.

Saw a bunch of passenger side ones for sale on eBay, and want to make sure those work on driver side before purchasing. Will those work?

Please advise, thanks!!!

im going to say they are position specific. motors can sometimes go right or left but from what i remember from pulling regulators, the amount of mounting points and how the gears/track layout, they are side specific.

one option is to compare part numbers too

In anything I have worked on, they are specific to each door.

They are all different left, right, front and rear. The motors are different as well.
