That is correct for the 2007 Chevy Tahoe LTZ
Usually this a faulty signal light switch. The Signal light switch disconects the brake light on the signaling side and makes it flash.
If the turn signal bulbs light but will not flash, the flasher relay is defective, replace it.

1995 Chevy Blazer turn signal light bulb replacement: Purchase the correct replacement turn signal light bulb(s) first, before disassembling the vehicle. See sources and related links below for replacement bulb information. Then consult your owner's manual for the turn signal light bulb replacement procedure. As simple as it sounds, the owner's manual is the best place to start for bulb replacement instructions and illustrations. You may want to consider replacing both left and right at the same time in order to keep brightness and color equal (optional).
I haven't done this on my Blazer yet but my manual says to reach up behind the bumper to the light socket, twist it and it will come out of the housing with the bulb so you can change it.
I may know the answer if it is a full size Blazer. There is a ground wire for the socket that may be connected to an area that has rusted and no longer is grounded. Reconnect to a solid piece of metal for the light to work.
No answer. Haha!!!
b/c light fool

To tell you to read the diagnostic codes.
