2002 Sonata AC problem
I have a 2002 Sonata 4cyl. that after the AC has been blowing a while a mist
will come out of the vents and then the pressure will go away. It will still blow slightly and the temperature still seems to work. You just seem to loose pressure. Any ideas? The dealership of course says that it does not do it when they have it in there so therefore they can not fix it. |
Re: 2002 Sonata AC problem
What do you mean by losing pressure? Do you mean that the blower fan slows
down or that the air coming out of the vents slows down or stops? (I presume you don't have automatic climate controls). |

On humid days that can happen. If you turn the A/C off for a few minutes but leave the fan running on high it would clear up the problem temporarily, if that's what's happening. To avoid it, you could try running with recirculated air on humid days. Harry |

The 'mist' you are seeing is water/water vapor being forced out of the vents by your fan. It sounds like the AC is freezing up. If the humidity is really high this can happen. Turning off the AC and leaving the blower motor running will melt the ice and restore the airflow. If it happens continually I would suspect that the temperature cutout switch is not working, it is designed to cycle the AC system off once the coils reach a preset temperature to help avoid icing.
