Truck shuts off on a.c.

How did you replace battery? Proper way is, negative off, positive off, positive on, negative on During this keep other cable from touching anything metal or the post. Have you checked fuses?

It was changed at auto zone by one of there employees not sure how they changed it and yes fusses are fine the ac/heat comes on but only through floor and wind shield vents but as soon as you cut it on if you don't push on gas a little the truck shuts off
