Where is the power window circuit breaker on a 1996 GMC Sierra Pickup truck?

The 1996 GMC Sierra doesn't have a dedicated circuit breaker for just the power windows. Power window functionality is controlled by fuses in the fuse box(es). There's usually an underhood fuse block and an interior fuse block (often under the dash, sometimes in the glove box area).

To find the correct fuse(s), you'll need to consult your owner's manual. The manual will have a fuse box diagram showing which fuse(s) control the power windows and their amperage. If you don't have the manual, you can often find a digital copy online by searching for "1996 GMC Sierra owner's manual PDF".

Important Note: Before checking or replacing any fuses, always disconnect the negative terminal of your battery to prevent electrical shorts.
