问：乘客的侧窗不起作用。

Not only is being unable to roll down your Tahoe’s window a frustrating situation, it is also a safety concern too.If you are attempting to roll down your vehicle window through its’ electric button and either nothing happens or you hear a click sound, then there are a few things that could be going on. The more common issues I have experienced over the years include a bad window switch, a broken window regulator or a failed window motor. Since a window being unable to be rolled down is an electric issue, I highly recommend enlisting the help of a certified mechanic to go over your car and检查问题。他们将能够相当快地解决您的窗户问题，并让您知道您的维修和零件，您的卡车将需要使其窗口再次正常工作。
