Electrical issues??

So help needed. Driving like normal with the ac on, the abs light comes on, and the air bag light also comes on, and the transmission starts going crazy, not shifting etc . Turn the ac off and it drives normal. With the ac off, all the indicator lights are off. I use anything electrical and the lights go on and the transmission goes haywire. Please help,

OBD works, I'd start there.

Sounds like a low voltage condition to me, though. Like your alternator is dying. Does the battery light come on when you turn the key on and go out once the engine is started?

Had the battery tested, bad battery. Just put the new battery in, hopefully that is all....... for now anyways
