I have a 1998 Chevy Blazer. It was running fine and then I tried to start it and it and it wouldn't start. It doesn't turn over it just makes a clicking noise. I'm confused because when I intially go to start it the lights work fine and the radio works and then when I try to fire it on, it makes that clicking noise and then all the lights start to dim. HELP!!!!!!

Could be either the battery or the starter/starter solenoid. Check to make sure your battery posts are tight and there is no corrosion. Check your wires going to the starter and your ground. If that's not the problem, take the battery and have it tested. Autozone or Advance will do it for free. If the battery checks out fine, they will also test your starter for free too. Your ignition switch could be faulty also but check the battery and starter first since they are alot easier to test.

sounds like a bad battery get it load tested
i would say its junk

Ditto on the load test on the battery, heat can be as bad on a battery as the cold can be...good luck

Definitely sounds like battery and/or battery cable.
