Started having air conditioning issued a couple of days ago. It all started noticing the AC not getting cold fast enough, original thought was the refrigerant was getting low need to recharge... but then on my way from work I noticed something weird... the climate controls stated the blower should be on the upper dash vents and on the highest blowing setting. Started to put my hands against the vents noticed the driver side was blowing very low and warm. BUT the passenger side was blowing high and cold! I then continued to drive and the driver side upper vents started up as normal... then with cool air? Thought it was a spoof and turned it off and turned it back on. It remained cool and blowing hard as it should. Next day, on my way to work. The AC started acting up again. Instead of air blowing out the passenger side on the same settings as the day before, it was blowing warm and hard out the driverside... but no air blowing in the passenger side with a slight feeling of cool. I then start feeling around and found the AC with cold air was coming out of the passenger side floor vents when the settings were on the upper vents.
I looked to see also if the refrigerant was the cause but the refrigerant was low...but after trying to put some in I noticed the gauge on the arctic freeze to go up and while holding down on it, the Guage would go down.

All in all, I am mind boggled on what's wrong.
Any one experience this before?

 

 

This is awesome. I will try this in the morning!

 

Okay, so I did the self diagnostic tests and appears nothing wrong. Now both upper vents blow evenly, but now it's still only 1 side with ac.
