My AC has been a bit intermittent this year, I had it regassed a couple of weeks ago and hoped that would cure it, but alas not. Typically, it will blow cold for about 15-20 mins, and then it will blow ambient air for approx 30secs a minutes, and then cold for 30secs - minute etc and it repeats this pattern.

I have scanned it and got three codes:

3 Faults Found:
01809 - Actuating Motor for Temperature Flap; Left (V158)
41-10 - Blocked or No Voltage - Intermittent
00716 - Air recirculation Flap Positioning Motor (V113)
41-00 - Blocked or No Voltage
01232 - A/C Compressor Regulator Valve (N280)
29-10 - Short to Ground - Intermittent

I'll be googling later for ideas, but in the meantime wondered if anyone with more AC experience than me can shed any light on those codes (specifically the N280 one)
