Might be late with this but I believe it has to do with a recall.

Need a little more info! Does it do this at a steady hyway speed, or are you in stop & go traffic?

Steady highway speed.

Only thing i can think of is it's possible it needs a shot of freon. Sounds like the compressor is cycling on/off due to low pressure. Hard to tell without some pressure readings.

I had the compressor checked and it is holding pressure. They also said that the freon was good.

When you say warm air, is it warmer than ambient temp.like maybe the heater on? If that is the case, possible blend door actuator problem. That's just a guess. But a fairly good one i think!

This is what I was told culd be the problem. How much does this cost to fix?
