As I was driving my Cadillac around I heard this noise in the rear passenger area.I looked back and the drivers window was down just hair and there was the noise.As I proceeded to raise the window and when I did the window just dropped. I called SERVICE STREET highlands ranch and told them the problem and they told me absolutely is now a good time ? I was shocked, I made the guy say it again do to I cant believe what he just said ,RIGHT NOW .I said RIGHT NOW?He said yes. Long story short it needed a window regulator and they ordered one from the manufacture and installed it in a timely manner and I was on my way, THANKS to the staff and the mechanics you guys are GREAT.
