My 1993 Pathfinder doesn't start when I turn the ignition. It doesn't make a sound. I changed the battery but that wasn't it. I believe it could be the ignition switch. I'm not a mechanic but any advice on how I could fix it would be appreciated. I probably drive it about once a week and it has apprx 87k miles on it. Thanks for your help.

when you turn the key, do the interior componets power up, IE: radio, blower fan....

You can also apply a test light to the Positve pole of the starter and make sure you are getting juice down there....
