Hello mr.kilmer I've got a driver side electric window that screeches every time I roll up the window. I've tried spraying lubricant but it doesn't really work. Do you have any idea what I can do to fix it?

Silicone spray lubricant is best for this. Sometimes you do need to clean the tracks with a cloth, wiping down the inside of the tracks with the silicone on a cloth. Had a friend say this wasn't working for him so I stopped by and used about a 3rd of a can of silicone spray on his windows. All they needed was more spray before they began operating smoothly.
You left out a few details like what kind of vehicle you're dealing with and how old. If lubricating the window track with silicone doesn't fix the noise it is probably coming from the window regulator inside the door, possibly from dried-up grease if it's an old car. Another possibility would be the window scraping against a rubber seal on the door which has hardened.

@chucktobias like... they assume it's not relevant > it's a convertible
keep spraying. You didn't get the right spot.
Scotty recommends only spray sillicone in a can (it is waterproof) or you will need a new window regulator motor assembly
