I have a 98 cavalier z24, and the problem is that some of lights are not working, specifically my passenger side corner light and fog light and occasionally my driver side fog light will not work. All the bulbs are fine(new in fact) and I tried to change the relay beside the passenger side headlight and that has no effect. Any thougths and or suggestions of things to check would be appreciated. Thanks in advance.

Do you have a multimeter? You could check for continuity. To me it kind of sounds like a connection problem.

Although Im no expert by any means.

I would check the relay connector for continuity.... I had a similar problem.... what fixed it was replacing the connector + 4 inchs of wire.... the always hot wire (i think it's labeled 30 orange) is prone to arc due to always being hot... and can burn out the wire
