Dash lights don't come on during the day until I turn on parking/head lights! on 2005 Chevrolet Silverado 1500

When I turn off parking/head lights during the day,dash light go off. At night when the head lights come on automatic my dash lights work fine.

Normal operation, daytime running lights do not illuminate the dash lights. Only the headlight switch or auto headlight module does.
Thanks for the reply, hard to see speed or radio during the day, also friend has ,06 dash lights are on during the day. Thanks for helping all of us Jim
