I am helping with a 2004 Chevy Avalanche Z71.

The right headlight comes on randomly. The lamp is very dim. The vehicle has been off for hours/days. It is locked and unoccupied.

No other lights are illuminated. We looked through the drivers window and there are no dash lights or interior lights on. No tail lights, marker lights or front park lights. The left headlight is not illuminated.

We are looking for suggestions and ideas where to start. The battery is less than one month old. This was occurring prior to the battery change.

Thank you in advance for your assistance.
