AC stops working out panel vents after few minutes of blowing cold. Turn defrost on it blows cold out defrost, turn back to panel it works for few minutes then blows warm again.

Air Conditioning problem
2007 Dodge Caravan 6 cyl Front Wheel Drive Automatic

I get an occasional mildew or mold odor from my Air Conditioner. I have tried lysol and today I took it to a shop who used another product, yet the odor came back on the way home. My wife is ready to get rid of the car. Can you advise what to do?

did you change the cabin air filter?

There are different cleaners on the market, some don't work or some don't get in deep enough to the are needed.

I would contact the shop that did the work and ask why it didn't work. They may well do it again at no charge. That is where I would start.

Yeah blue for cool. Red for bad, hot, blood. ok You can't really hook it up wrong, the fittings match up. Always put freon into the low side-Blue
