My driver's window rolls up faster than my passenger window.
They both go down quickly, though (not talking about driver's auto-down).
I guess that means I'll need a new window motor soon. That sucks.
I'm not looking forward to pull off door panels. I did enough of that already on the Berettas to swap the tinted glass. And puling them off to dye them black. Not to mention removing them to fix a door lock issue. God, I'm sick of looking at the inside of car doors! LOL.

 

Would "the big 3 upgrade" fix this?

 

It would on a system that's working properly, but for one that's showing signs of failure: ie, a relay going bad, or a bad auto down module/motor, it would probably accelerate the offending part's death, lol. It'd be best to do a thorough check of the window's electrical components to determine what's at fault, and then do the "B3U"

 

theres no need to do the big 3 update if your not running a high powered anything. the only reasoning behind the big 3 is to match the stock power cables under the hood to your new aftermarket one running through your car. example, 4 guage speaker wire ran to amp

 

Actually, upgrading the ground cables IS a very good idea on any car over 4 years old regardless if the car has a system or not, specially if the car begins to show problems of electrical components. Once the OP find the problem, upgrading the vehicle's wiring to the alt and grounds is not a bad idea.

 

what is the big 3?

thanks. i'm not to tech savy, i mean i could probably do this but would a shop be able to do this?

 

majority of shops will look at you funny but most know what you are talking about expecially the shops that just bo car stereo instanns and amp installs they can do that with ease for you

 

i really really really dont think the big 3 would help your issue. the big 3 would definitely help any electrical system but if your not drawing any extra after market voltage i dont think the big 3 is at all necessary. cleaning grounds is always smart but if 1 of your windows is giving you issues and nothing else than its definitely an issue with the window and not the electrical system. dont spend the money to get the big 3 done because it will not fix your problem. chevrolet gave the stock electrical system more than enough voltage to run your car normally but if you exceed the norm then thats where you need to start beefing up your electrical.
