Hey guys, need a hand with my kids 93 Altima. I figure there's more experience on a forum than anywhere. She brought it to me saying heat wasn't working, next morning it wouldn't start, I thought it was ignition switch and replaced it, still nothing. Everything else works just won't turn over. Checked fuses, played around with relays. Lights won't dim when turning key, security light is acting as it should. My next idea is to jump starter. You guys have any ideas?
