When I use the drivers side window buttton to raise the passenger window, sometimes it works OK. Other times the window goes up 3/4 of the way, and then back down to 1/4. I then need to hold the lever in continuously to get it to go all the way back up. When I work the window using the passenger lever it works fine.

Is there somethimng I am missing or is my CS acting up? By the way it was sligthly less than 600 miles all of which were put on in the last week (it was a newly purchased 2007).
