Break Lights Not Illuminating
My 2007 Tahoe LTZ break lights will not illuminate when i press the break. The light across the top will illuminate, but not the two bottom lights. I've replaced fuses and bulbs, and I tried to replace the break light switch, but it made it look like the breaks were pushed even when they weren't. The bottom lights were still not working with the new switch. Is there anything else i can replace?

If the fuses (BCK/UP STOP , LT STOP TRN , RT STOP TRN) are OK. Give the computer (BCM) a reboot, disconnect/reconnect the battery. The stop switch sends a signal to the BCM, which then turns on all stop lights. The brake switch appears to be functioning since your center brake light is working. "Back in the day" the hazard and turn signal switches would be next to check but, nothing goes thru the turn signal switch anymore.
