Default Slow & Intermittent Windows

Hi all,

I'm experiencing extremely slow auto roll down on my 2 front windows. I'm guessing the window regulators aren't shot because they sometimes quickly go down on their own when I try to roll them up.

Should I try lubing the seals? Anything else to look out for?

Also is there a reset pattern on the LS460? I know I had to do one on my RX330 after changing a battery.

Thanks!

Sounds like it is time to take door panels off and start lubing all the tracks/gears. Should be pretty basic

Check the seal on the rearward/vertical part of the glass, as all or part of it may be binding and getting trapped on the inside of the glass. Been using Shin-Etsu silicone grease for years and it works well to make the rubber more pliable:
