AC stopped working after winter passed even though AC button is on. Told no fluid leaks or other known issues. Was told IPDM needs replacement due to A/C INOPERATIVE WITH DTC B20C8-14 STORED IN THE IPDM E/R. Have found several other people online having the same problem. Nissan stating problem is only part of a service bulletin and therefore not a recall. Requesting further review/investigation since it seems to be a common issue on this model and in my opinion should be a recall. I understand my opinion and facts of further investigation may not prove as such but without the complaints how would you know. Thank you
