Hey found alot of useful information on this forum so I decided to make an account to ask other maxima drivers for some advise.

Awhile back I got some work done on the AC system of my 1999 infiniti i30 and got the compressor replaced, mode door actuator replaced and blower replaced and everything heat/cold ac worked fine. Later down the line my alternator was dying and me and my dad replaced the alternator, but to do that you have to unmount the ac compressor and set on something out of the way to access the alternator. We were gentle with it, but i found that after the fix my a/c no longer blew cold, and I was afraid that we damaged the compressor or something like that. But it appears the a/c and heat do not work, it just blows air whatever temperature it is outside, If i turn it to heat, it doesn't warm, if i turn it to cold, I hear the compressor kick on but the air does not become cold. The fan speeds and direction work fine. Has anyone had this problem? Thank you for any information, and I will be happy to provide photos or additional information if anyone needs

 

oops sorry! I just say the infiniti i30 board will post this over there aswell, sorry for the trouble mods.

 

Gort, since the Infiniti is essentially a 4th gen Maxima mechanicly, it's fine to post on the Maxima side.

 

To confirm, digital or manual climate control?

If digital, run through the diagnostics procedure (see thread below on how to do this). If manual, does everything work on speed 4 but not other speeds?

W/o more info, it sounds like your air mix door actuator has failed.

Thank you for the help, it is a digital climate control, I will read that thread and see if I can manage to do it. I have an old estimate of the repairs I got done on the A/C i will find it and post all that was replaced on here. It worries me because I think I had that replaced but not positive. Off the top of my head it was the a/c blower, compressor, mode door actuator.

EDIT* ok I have downloaded and printed the self diagnostic test for the i30 and plan to run through it today or this weekend, I will post here with results
