volts ?
I took a pic ( not the best) but my volts seem to be getting lower and lower every time i drive you can see the needle is on the red and sometimes it gets alittle further , this is sitting at a red light . Does it look like my alternator may be going out ? Thanks for the help

underdrive pulley?
if you can, try to check the voltage directly from the battery, to see what kind of voltage you are seeing.
in the heat of the summer you will typically see a little less on the gauge but if you see anything less than about 13 volts than you could be having issues with the alternator

For my understanding sitting at a light especially with the AC on they will just ride low like that. If its going back up to normal when youre driving down the road its probably good. If its not killing the battery and starting every time there is nothing wrong with it odds are

If thats what it is doing and you have no issues starting everything is most likely fine. Mine does the same thing. Did the same thing when I had the old alternator and the new one. I wasted the money getting a new one. If you call GM they will tell you if you have the air on and are sitting still its perfectly normal. As long as no issues starting and it comes back to where it should be when cruising youre fine
