Can the wrong battery cause AC not to work?

Asked by Terri-Lynn Jun 26, 2020 at 12:39 AM about the 2012 Volkswagen Jetta SE

Question type: Maintenance & Repair

I changed out the battery in my Volkswagen Jetta SE to a 650cc one I bought
from Walmart. I never owned a car like this before and I am not thinking I
shouldn't have bought that battery. Since I have replaced the battery, my a/c in
my car has stopped working. Not sure if it is possible but do you think the
battery could cause the a/c to not work?

Nope. Perhaps a wire was disconnected under the hood or a fuse was blown.

On many newer vehicles when you change the battery the computers need to stay powered up. If not you can find yourself with accessories like the air conditioning not working. You'll probably need to have the computer flashed to get it working again. Next time use a memory saver before disconnecting the battery. Hope that helps! Jim
