Can anyone help answer some problems with my 2005 chevy trailblazer? The

[steph01]

problems started with dimming? headlights, and then power locks starting making a clicking sound when vehicle is first started. And then yesterday we filled the car up with gas and gas gauge went to Empty, and finally would not go into 4 wheel drive today? Anyone had these problems?

start by getting your battery fully charged, sounds like it's going bad. Possibly a loose battery cable or wire to starter is loose.
all these symptoms are from using lots of juice from the battery.
