2003 Chevy Tahoe. If I turn car off and open cargo door, for even a few minutes to load something, the battery drains and I can't start without a jump. What is that?
Started out of the blue and is very irritating. Sound like it's the starter because of clicking
when you turn over, but starts right up with jump and is fine until I forGet and open the
cargo door with ignition off. I can open cargo door if engine is running and it does not
affect start up.
