2000 Chevy Astro dash lights dimming in and out

Noticed yesterday my dash and radio lights fading in and out..mainly when shifting from park to drive..any ideas?

you may want to check your charging system. and your idle air control if your idle dips too much when your trans goes into gear. Just it just dim once as your trans goes into gear or is it dimming and getting bright many times?

It was flickering in and out as I was driving..hasn't done it in a few days ..but the other day my left blinker stopped working..checked my haz lights..they worked and then ttried my left blinker and it's working again...weird

if it continues you should look at your battery voltage when it is happening. the turn signal is different. the switch may be getting a build up from arcing on the contacts. wait and see if it gets worse.
