My high beams were stuck on unless the left turn signal is on, so I put on a new turn signal switch. No more constant High Beams, however the auto lights I think are not working. When the old switch was on auto the icon would light up and the body lights with headlights would be on. I'm wondering, did I get a bad switch?

You could have a bad switch or the wrong switch, here is the correct part number for the switch and instructions on how to change it correctly.

Turn Signal Switch : 20808029 $107.04

Can I ask if the switch is aftermarket? Check out the images (below). Please let us know what happens.
