Low beams not working - 2007 Chevy Tahoe

[HarryPrescott]

2007 Z71 Chevy Tahoe. Low beams not working. DRLs and high beams work fine. Checked bulbs and fuses - no issues there. Next step?

Sidenote - recently replaced brake light switch to fix cruise control failure.

First time poster, any help would be much appreciated.

Live on the Treasure Coast by chance? An advanced scan tool is needed to see what's going on inside.

Going to ask the mods, @NathanJax, to put this in the right forum for more help.

I think some of the early models may possibly have a ground problem, if you have a multi meter pull the headlight connector off and check which wire is the ground then patch in a ground wire straight to the frame and see if that corrects your issue, it wont hurt anything to do this, mine are grounded to the frame for a HID system.
