Recently the front windows in my lancer has started to make squeaking noise when rolling them up and down. Its not that loud but loud enough to bother me

Well it sounds and feels like the inside (dont know the mechanics) is dry and thats whats causing the noise. I believe on rainy days that sound disappears and it comes back especially on hot and dry weather.
The idea of putting some form of lubricant comes to my head but you guys are the expert so please advise what and how to do?
cheers,
Mick
