HI there,

I have a 1997 Kia Sportage and the fuse box is missing the cover that specifies what goes where. Does anyone know where I can find an image or reference of one?

There should be a description of the fuse locations in your owners manual.
Another options is to acquire a replacemet cover from another like vehicle, like from a salvage/junk yard vehicle.
Are you having any specific fuse issues we can help with?

I don't have the owner's manual, hence my question here. There is no guide online? No, I just want to make sure they are all there and working. And need to know what is what. Also,my electric windows are not working and I want to make sure that it's not the fuse before I replace the motors.

I'd give this site a try Online Repair Manuals (http://www.carspace.com/guides/Online-Repair-Manuals)

Oh, well, the windows have two fuses that could be an issue.
Do any of the windows work? Or none work?
Does the rear wiper work? (Odd question but it's fuse is related)
Check the P/W (for power window) fuse (passenger compartment fuse block). That is a 30 Amp fuse. Let us know.

Also, as for the other fuses, the best thing to do here is let us know if you have any other symptoms or if any other system gives you problems.
