I have a 2010 CX-7 black paint, black interior. The A/C seems to blow cold but never cools the car off. We have recently moved to a warmer climate and i suspect that the issue is that since the car is all black and the CX-7s have a huge front window that the car is just heating up too much inside and the A/C system just isn't capable of cooling the car after its been outside in the sun for a while. I've taken it in twice and both time the diagnostics come back clean, the coolant gets recharged but doesn't seem to make it that much cooler than it was before. Has anyone else had this issue?

 

I have an '08 I bought last fall so this is the first season I've used the ac. It is a little weak...and I've read a few reviews that complained of the same. I also have a black interior and it was taking a 3 or 4 minutes and/or miles down the road to start blowing cold. I recharged it myself with a partly full can I already had and it did help some. It is still about 1/2 into the 'safe charge' zone on the pressure gauge. I plan on getting another can and max it out to see if that will improve it.
If yours is not blowing cold air, you've got a problem somewhere.

 

I have a CX-7 2010 and it's a freezer! ICE COLD.

 

Run the AC on speed 2, face vents, recir, doors & windows closed, stick a digital thermometer in the centre vent. Depending on ambient temps you may need to let it run for 10 -15 minutes. Watch the temps as it cycles, should get down to about 5 degrees centigrade / 40 degrees fahrenheit, & cycle up to about 7c / 45f
Go for drive at medium to high speed & monitor cycle temps.
