Curious if anyone could help me. I have a 2002 grand am, and for some reason when i roll the windows up or down while driving it makes my rpms go up also if i have cruise on, and roll my window up or down it shuts the cruise off and I have to reset it. If anyone has had this problem or if anyone knows be a great help.

my guess is u have wires crossed somewhere. thats the only thing i can think of. im not to sure on how to check for that tho but thats wat im thinkin is wrong

well the windows do put a drain on the electrical = lower rpm, but I'm not sure about why it would cause cruise to go off - maybe it's designed that way so you aren't rolling down your window while your car just drives itself.

yeah that is possible, they are adding new safety things everyday maybe its just part of that :( just annoying sometimes lol

Curiosity struck after reading this thread, SO i tried cruise on my 02 GT and opened and closed windows... cruise stayed on. If i had to guess the cruise control switch is probably going bad. My cruise was acting funny with the radio controls on mine at one point before i got it all replaced. If the car is still under warranty have the dealer take care of it....
