All lights comes on when the air conditioning runs for a while. All lights come on but the car does not stop running. The windows will not roll down. What could be causing this?

Good morning.

Can you explain a little more about what lights come on?

Does the air conditioning work okay?

Do the windows stop working when all this happens or do they not work all the time?

All the lights on the dash, notifications lights come on battery, seat belt, engine, etc. Yes the air conditioning still be blowing, the windows do not roll down when lights come on, unless I pull over and turn key off then the lights on dash go off and power resumes to the windows. The gauges on the dash also go to the off position as if I turned the car off. But the car still be going/running. I uploaded a picture of the dashboard with lights on.

Thank you.

From the looks of it, you are loosing communication. This could be from the ignition switch which is common for this issue.

I suggest you get it checked to be sure.
