A/C suddenly stopped working
I had just replaced my battery yesterday probably has nothing to do with the issue just wanted to mention it. Today I went to start up my car and the ac/heat wouldn’t blow at all, I tried turning the car off, turned on max cool, raised/lowered fan speed. Luckily it was nice out so I drove off and 10 minutes into my drive my ac turned on like nothing was wrong, any ideas?

I'm extrapolating from your second sentence that your Blower Motor is not working and or the resistor for it is going bad.
If your AC compressor and all is engaging and it's just not blowing air it isn't the AC side having an issue, same with heat.

Any ideas why it would suddenly work after 10 minutes of driving, would that mean its for of an electrical problem than the blower motor actually going out. When it worked heat and a/c worked perfectly fine
