Daniel's Denali

i did drilled and slotted powerstop rotors and they were ballin af. never warped or cracked like some ppl say on here. they looked sweet and were only like $100 a pair.
 
I just recently installed the Baer eradispeed +1's. Look fricken wicked and stopping power is spot on
 
So last night I was sitting in the driveway with the key on acc for a bit, "service battery charging system" pops up and I try to crank the truck and it was dead as could be. I waited like 20 minutes and go to crank it and it started right up. But now, with my a/c on cold, it blows ice cold on the driver side and blows painfully hot on the passenger. Wtf is going on
