Drained or Dead Battery in a Chevrolet Astro

The most common reason a Chevy doesn’t crank is a dead or weak battery. Your battery delivers the initial burst of electricity to turn over the engine and get it running.

Indications of a dead battery:

  • Silence upon turning the key – no clicking or turnover
  • Electronics not powering on
  • Difficulty starting in cold weather

How to Fix It: Keep jumper cables on hand for a dead battery emergency. Jump starting your Chevy Astro using a good battery or portable charger can deliver enough juice to get it started.

You can also clean corroded battery terminals that are blocking a good connection. If problems persist, have your battery tested – it may need replacing if old.
