I have about 20,000 miles on my Kona. I just had the battery replaced and not the air conditioner isn't working. Also there is no way to control the heat coming out of the vents. Any help would be appreciated.

Thank you.

 

Do you hear anything when you switch functions on the heater controls?

Are the air controlling doors working or attempting to work?

 

No nothing just the hot air from the vents.

 

I'd just take it to Hyundai for rectification under warranty. Is there any reset procedure in the user manual? Seems strange it stopped with a battery replacement unless the controller in car did not like power removed.
