2006 Charger Daytona
The AC works great until the outside temps get over 95F. Once the temp goes above that, the AC will start off cool and then progress to blowing outside air in. The air smells musty, probably because the compressor kicks off and it is blowing outside air. Basically at 6am in the morning I drive to work with cold AC, when I get off at 2pm I drive home with outside air AC, not cold. So if I park the car in the shade (under a tree or a canopy) the ac will blow colder for a longer period of time than if I park it in the sun. This seems to be in conjuction with the temp of the car and the temp of the outside. Somedays I can drive almost home without the compressor cycling off, other days I am slowly melting. But I can enjoy colder air for a longer period of time if the car is parked in the shade. The fan (under the hood) will come on and off with the compressor when the compressor goes on and off.
Morning hours and Night hours the AC works without a flaw, no issues at all. This is a heat of the day, out in the sun issue from what I can tell.
On the computer you can see the compressor turning off/on along with the fan (cycling if you will) when it is doing this.
Things to rule out:
The system has been vacuumed and recharged to all specs. Had a independent do it (same problem) then the dealer did it ... so the charge is not questionable
Dye has been added and we do not have a leak. Checked several times, no leak
High Pressure Switch has been replaced. Still same problem
Dealer is still scratching their head on this one.
TSB is done also. Flashed it twice just to make sure, still same problem
We have had it hooked up to the StarScan and can watch the pressure come on and off - you can hear the fan kick on/off at the same time.
Sometimes the StarScan will show that the AC button on the dash is not pressed, when it is.
The only code I get is p0532 which is low pressure AC line something or other.
Dealer is thinking the upper control module may be the problem. What I am referring to is the silver box mounted to the fusebox under the hood.

So with the above, what do you think the problem is? Again it works just like it is supposed to except when the outside temps exceed 95 F .... then the AC is on its own program. I will be driving for 20 minutes with warm air blowing out, then the air will begin to cool down again. I have not noticed a pattern to this problem as of yet.
