Air Conditioning problem
2004 Acura TSX Automatic 51000 miles

Over the past few months I have been having problems with my air conditioner in my 2004 Acura TSX. First, it was only blowing hot air--no cold at all. The shop at first thought that I needed a new compressor but then changed their minds. They replaced a compressor switch(?) And replaced the left fan. Now I have found that when the atmospheric pressures are high as with high humidity days, the air conditioner does not blow cold air. The air that comes out is like if only a fan were on not air conditoned cold air. When it is not humid, the AC seems to work fine. It's as if the air conditioner will not " kick on" if the outside atmospheric pressure are elevated. What could be wrong?

Hi ynkeesluvr,

Thank you for the donation.

When the AC don't blow cold, there are many possible reasons so you need to do simple checks to narrow down the sources.

Check for
1. Radiator and condenser fan operations.
2. Power supply to Compressor and operations. Is compressor on full time?
3. Radiator Coolant level and temp reading.

We need to know the above to be able to continue with our analysis.

According to the shop when I first got work done, after the left fan was replaced both sides now work. The shop " topped off" the coolant and is at the correct level. As I live in Florida, the AC is on Auto and is on every time the car is on.
Does the outside atmospheric pressure affect how the AC functions when in Auto mode? Today for example it is very humid and 84 degrees. My Auto AC is set at 70 no matter what the temp. Today the air is blowing out at a tepid temperature. I lowered the Auto temp to 60 and there was no change in the coldness of the air coming out of the vents.

Yes, when set to Auto, the ambient temp would affect the AC temp.

Try using manual and see if the temp works ok.
