There isn't a single universal fuse number across all 1997 Grand Cherokees; the number and location can vary slightly depending on trim level and options.
To find it:
1. Consult your owner's manual: This is the best resource. It will have a detailed fuse box diagram showing the location and function of each fuse.
2. Look for a fuse labeled "Power Windows" or something similar: The labeling might not be perfectly clear, but it will be close. You may see a fuse labeled for a power window motor or a related power accessory.
3. Check the underhood fuse block diagram: If your owner's manual is missing or unclear, the underhood fuse block usually has a diagram printed on its cover or inside the lid.
Important Note: If you suspect a blown fuse is the problem, always turn the ignition off before checking fuses. If you replace a fuse and it blows immediately again, there's a more serious electrical problem that requires professional attention. Don't keep replacing the fuse repeatedly, as this could damage the wiring.
