    I just replaced my 12v with an Optima, now the A/C or fan motor doesn't come on! It's like 100 degrees here. No codes or lights on the dash...

    Replacing the 12V battery would not cause that. Does everything else work on the car?

    Yes everything else works. The A/C was working, I replaced the battery, now it doesn't come on.

    Never mind, it just kicked on. It was probably 30 minutes or so not working. Maybe it needed to relearn something?
