YOU GUYS HAVING COMPLAINTS OF THE 08 SD HAVING LACK OF AC COOLING?

I know this was mentioned here not too long ago and there was an SSM out on this but I can't seem ti find either. It's a known concern. The original fix was to disconnect the MAF and turn on the key for 3 or 5 seconds then shut the key off. Reconnect the MAF and then clear the generated DTC's. It worked... but the new PCM calibration fixes the concern.

19683 replaces the one I loosely outlined... but it is better! The original gives you instructions to get the A/c working but all those trucks are being recalled for the recalibration so, it is pointless to perform the steps now. It he new calibration does not fix it then it's DIAG TIME!
