My windows in my Maxima go up kinda slow, in fact it is a bit embarrasing! At least they go up though, Its basically just the front windows. When they get about half way up they start going really really slow, is it because of the strain on my battery and the motors aren't getting enough power. When let them both up and close the sunroof they are super slow.

 

Try dry silicone, try doing a search or look at the FAQs. Try that first before you post. Alot of basic stuff can be resolved that way.

 

mine go up kinda slow since my windows are tinted

 

I am going to try dry silicone to see how this works. Where can I find this at? Advanced Auto Parts maybe?
