BATTERY EXPLOSION, a/c not working, 2014 silverado

Recommended Posts

A few days ago I turned the key to start my 2014 Silverado LTZ 4x4(51,000 miles), when it hit the accessory position my AC delco battery EXPLODED under my hood (spewing acid all over, the whole 9 yards). No, I don't have anything extra hooked to my battery at all. Anyway, this blew one of the main fuses coming directly off the battery in which I had to replace that entire fuse board. Bought a new battery, start the truck, radio screen not on. Found that little yellow blown fuse on the passenger side, fixed that. Now, for the life of me, I can not find the source of my last problem which is my A/C  blower motor will not come on at all.All the lights come on the a/c controller by the radio. I figured it would be another fuse but the ones I checked were ok(maybe I'm missing one?). I stabbed a test light in the red wire going to the blower motor and its getting power. It would be hard for me to believe that the blower motor went bad since it was otherwise working fine before this battery failure. What am I missing? Thank you in advance.

Does the voltage change at the motor when you change the fan speed? If so, it would seem like it’s working. I would guess full speed, the motor should be reading somewhere around 12-14 volts.

Just from what you’re saying though, if the fans getting power and isn’t moving, unless there’s a fuse on the fan, I’d guess it was toast. Could be wrong though.
