99 rear door lock actuators?

Hi, my wife's daily driver is a 99 xj. As she is hauling kids around, she really wants the electric door locks to work properly. I replaced the actuators in the front doors and those are working great now. The rears are still an issue. New units don't seem to be available on any of the sites I've checked.

Are new rear door lock actuators available anywhere?

Any chance the fronts would work? It would have unneeded clips for the key lock, but other than that they are functionally the same?

If I can't get new ones, I'll try pulling them, soaking in degreaser and relubing.

Any other suggestions? Thank you.

The rears have the child lock switch - so are different.

I have a set if you are interested pm me.

Thanks. I'm going to pull them this weekend and soak in degreaser, then relube and install. I'm hoping that brings them back to life for a while.

Keep an eye out on Ebay. I've bought spares over the years.
