    What exactly do you see and hear when you try to start it?

  • So does it crank or not? Jan 22, 2016 at 9:26
  • Are you sure the vehicle's transmission selector is fully in the park position? Put it in neutral and try to start it in that position. If all of the lights are working and you don't see as how they are dimming when you go to start it, it might be that the neutral safety switch is not working. Jan 22, 2016 at 16:54

Keep in mind that you can have a low battery and not be able to crank the engine, but still have enough to run some of the interior electrical parts like the one you mentioned. The fact that it's only been an hour since the car last ran makes the soft battery a likely candidate.
The key (as mentioned in the comments) is whether the engine is cranking or not. If it cranks then there is some other problem, but if not, it's likely one of the following:

- Soft battery (Most likely)
- Bad solenoid
- Bad ground in the starting system
- Intermittent starter connection
- Bad starter

If the problem is a soft battery, and nothing electrical was left on during that hour, you might have a bad alternator that's not charging the battery well. The easy way to tell if it's the battery or not is to measure the voltage across it with everything turned off. To be really sure nothing is pulling current from it, disconnect the negative and then the positive battery leads. Now measure the voltage across it. If it's below 12 volts DC, this is your likely problem. Here's a chart of battery voltage as an indicator of charge state:

Battery Voltage vs charge state

I hope that helps to at least get you pointed in the right direction.
