The fog lights on my 98 SE do not work. The bulbs are fine, and the fuses are fine, but they just don't turn on. The next thing I tryed to check is a relay in the under the hood fuse box that is labeled as fog lights, but when I went to auto zone to get a replacement they said that they didn't have any in stock. Is there any way to test this relay without swapping it for a new one?
