However, there isn't a single fuse dedicated solely to *all* power windows. The power windows are usually controlled by multiple fuses or circuits. You'll need to consult your owner's manual to find the specific fuse(s) related to your power window circuit(s). The manual will have a fuse box diagram showing the location and amperage of each fuse.
If you don't have the owner's manual, you can often find a digital version online through the Pontiac or General Motors website. Searching for "2006 Pontiac Grand Prix owner's manual" should yield results.
