Power window does not operate on 2003 GMC Yukon Denali

My passenger power window stopped working. How do I test if it is a door switch (driver or passenger?) or regulator/motor problem. All other windows work fine. Thanks.

It's hard to describe without illustrations. Autozone have some popular workshop manuals for free on line once you register (for free) on their website http://bit.ly/autozone_repair_info. and get an online repair manual subscription. There are two companies that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselfers. You can get a one week subscription or year subscription very cheap. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have, much better than generic workshop manuals from parts stores and much cheaper than the factory manual try Alldata which is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online or Mitchell on line http://bit.ly/Mitchell1_Online_Repair_Manuals and get an online repair manual subscription.

You will have to remove the door panel to access the window motor. There are two wires going to the motor. You will need a test light, check for power at the motor when pressing the window switch up or down, if you see power. The motor is the problem.
