Also, i have recently gotten a weird message like : park assist off or my radio setting will appear on the screen. This only happens when i have no air

Hello, my name is***** for the question. It sound like a voltage issue. Typically this will occur if there is a bad connection at the battery or if the battery is failing. I would check this first.

Customer: replied 1 year ago.

I will check that and let you know. Will be tomorrow. Car not here right now

Expert:  FIX IT MAN replied 1 year ago.

No problem. Just let me know when you can.

Put a voltage test on it...12.5 but when we put the trickle charger on it, it needs a charge (not fully charged) so we will see what it does in a couple hours. Thanks for checking back.

Fully charged battery. Drove 6 miles, got groceries then drove 6 miles back. Had full cold AC.Car sat for approx 15 min then had BARELY cool air.

Expert:  FIX IT MAN replied 1 year ago.

Did you happen to check the voltage again afterwards to see if it dropped off again?

Customer: replied 1 year ago.

No, but i did have the battery checked and it is fine.

Expert:  FIX IT MAN replied 1 year ago.

Thanks. One question. When the air stops working does the fan and the control unit shut off or does it just blow hot air?

Customer: replied 1 year ago.

Blows hot air.

Expert:  FIX IT MAN replied 1 year ago.

Thank you. It may have a loose ground connection issue. This is where I would direct you to next. Did you plan on going through these yourself?
