07 Tahoe Interior Lights Flickering
 

Hello All,

I have a 07 Tahoe and recently the interior lights are flickering when I start up the truck. The insturment panel, dome lights, and lighting for the ac controls. I am not sure whats going on. Could this be the alternator going bad? If so do you recommend me replacing it with one from autozone or Oreily? Please help.

Thank you.
