I was "sidelined" on a day trip last week to Napa in 100 degre heat with 3 others in the car and AC full blast with a CEL and flashing up arrow. I didn't know how to pull codes so I let the car rest for a bit and when I turned it back over the lights were gone. Couple days before that I had flashing arrows on the AC once. The next day I figured out how to pull a code but only checked A1 and found 235. A week later (today) I pulled these codes and am lost . . . .

My findings:
A1: 111
A2: 325
A3: 444
A7: 122
B1: 325
B2: 122

I found the definition on another post for:
A7 122: engine coolant temperature (ECT) sensor interval too long
B1 325: recirculation damper motor active too long

Hope I don't sound like a moron (I actually don't care, new & eager to learn about this stuff!) but what does this mean and does it explain why I had a flashing up arrow with the CEL? What do I check. I DO have a high pitched "hiss/whistle" at certain points of acceleration, does all this constitute the vacuum hoses being replaced? Sorry my incident is so scattered, hard to find time. Thanks for helping me out if you will. -Stu.
