2005 Altima AC problems

[tvdummy]

My daughter has a 2005 2.5L saden. The ac was working fine then quit. Then she turned it off and on a few times and it started back working. It has quit again. The compressor is not kicking on. i see no evidence of any leaks. Checked the low pressure hose really good. I see a pressure switch on the high side(up by the raditor) Where is the low switch? Any ideas on what to check?? thx jb

I have had a few IPDMs go bad and cause A/C to quit working intermittently. I would not replace it unless you are sure the system has a full charge. I believe you only have the one duel pressure switch. They rarely go bad.
