fuse should be in the fuse panel in the truck , if you have a test light i would pull the master switch from the left door which just pops out just be careful there are tabs that break , and check for incoming power to the switch and then try power on the other side while moving the switch , if you have power to the switch and back out , next stop is the window motors

the fuse will be labeled windows , a test light is used to check for power it has a ground lead and the user end is fixed with a ligh and a probe , when its grounded and has power it pops the light on to tell you there is power at the source you are checking

Suggested Repair

Look in the truck fuse panel for a fuse labeled Windows. Carefully remove the left-door master switch, watching the retaining tabs, and use a grounded test light to check power into the switch and power out while operating it. If power is present in and out, check the window motors next.

Conversation Summary

The owner of a 1990 Chevrolet Silverado says none of the power windows work and cannot find the fuse. The expert says the fuse should be in the truck fuse panel and labeled Windows, explains how a test light shows power, and advises checking power at the left-door master switch before moving on to the window motors. The owner still cannot find a Windows fuse and asks whether there is another fuse box.
