Windows squeek/squeal metal sound

93 lx 4dr.  Power windows work, there is just a God Awful squeal out of the driver side rear window and a squeak, rubbing, metal sound on drivers window.

How would/could these sounds be eliminated?

I searched for a previous topic and did not see anything.  Thanks.

First try to lube the window run channels with silicone spray.
What ever door seems to have the metal to metal noise, you might have to remove the door panel, peel back the plastic liner, and then replug in the control switch and run the window up and down to find the trouble
