ABS and brake lights come on

Good morning.

The ABS system has stored a fault in the system. We need that fault or code. once we know the code, we can help narrow down the area of failure.

One quick check is to verify the fluid level in the master cylinder.

As far as the AC and the lights, verify all your fuses are good by checking for power on both sides with the key on with a test light.
