Powered side door - should I lubricate?

[FredFlintstone]

Just wondering, will be replacing the clips that hold the slide door guide rail cover in place next weekend.

Just wondering, it's all nice & clean in there, but should I consider lubricating the cables at all? Obviously I don't want to attract dust etc, but just thought I'd ask.

Would it be worth opening the black cover here and checking it's all OK within, .i.e. no corrosion etc & maybe add a little lubricant too?

Thanks
