2008-2010 Nissan Altima No AC Troubleshooting

[@mntunfreak]

I stumbled upon another reason why the AC quit. BEFORE you assume it's the clutch after checking the fuse, CHECK the 15A fuses for the blower motor under the dash on the driver's side. One of mine cooked while I was driving and smelled to high heaven. the smell is what saved me as it smelled when I pulled the cover off. ALSO, make sure you get the right fuses. It takes "Low Profile Mini Fuses" in that block. The idiot before me put mini fuses in by forcing them into the fuse block. I'm sure it had something to do with the fuse shorting out.

Question was your ac still blowing ? Even though the fuse blew

[@mntunfreak]

@@bassarcade424 I don't think so. It's been a minute.

Hello. My mechanic just vacuumed and charged my a/c. It cools good. However my clutch does not stop turning as long as my a/c is on. It stops when I turn off the a/c. When I tested this, the temperature setting was on 50%, just at the middle, and it was evening so not too hot weather. I waited around 5-10 minutes and the clutch did not stop turning. It was cold in the car but not very cold. When I turned the temperature switch to max, the air from the vents went colder. So the a/c temperature control system (probably some kind of thermostat) works properly. The only problem is that the clutch does not stop turning which increases the a/c gas pressure too much so it leaks out of the system. What’s the problem? How to fix?

Okay question my husband tried to jump off the compressor and to the backwards with the wires and they ended up melting what could it have messed up

[@georgephilpot5180]

Seems simple but limited room and nearly impossible allen bolt to get out. May wanna go ahead and hire a shop for this. I wish I had!

[@patgraeme775]

Thought it was just 4x 12mm housing bolts, 2x 10mm bolts for the H/L pressure lines and a 2 wire connection?

[@jimmyt2088]

ac blows air but no cold air, what do u think it could be? the 10 amp fuses were good am i screwed?

[@oldradio16]

if the compressor is not engaging and it has power to it then its the magnet coil

[@louressgreene5007]

oldradio16 what is the magnet coil?

[@parmreehal4773]

Currently having the same problem, were you able to diagnose it?

[@calvincristobal3234]

Same situation for me but I’m getting no power to it. But when I test run power to it from battery the compressor kicks in.. I don’t know what to do now because it’s not getting power

[@AN-kg4ei]

@@calvincristobal3234 low pressure switch or a fuse/relay I would bet... you can jump the low pressure switch temporarily and if that kicks on the clutch/AC compressor, you might have low refrigerant or a bad low press switch....

Hello I have an A/C issue with my 2010 Altima. Compressor clutch stays engaged all the time and the A/C does not cool down enough, just very little bit. I can not find the A/C compressor relay. Have any idea I can check and fix?

[@oldradio16]

If your compressor is on all the time and not getting cold air I would suspect your AC charge is to low, not a stuck really

[@MC-ph7gr]

@@oldradio16 I checked the gas in the system, looks okay

[@oldradio16]

@M C unless you have high side and low side it's not telling you a ton..if you turn the ac/ climate control off completely does it continue to spin the compressor?

[@MC-ph7gr]

@@oldradio16 When the A/C is off, clutch does not turn.

[@MC-ph7gr]

@@oldradio16 Well, my mechanic vacuumed and charged my a/c. It cools good now. However my clutch does not stop turning as long as my a/c is on. It stops when I turn off the a/c. What can I do about this?

[@Josephous]

mine did the same thing 09 altima, going to try to do the replacement this friday. how hard is the snap rings to get out without the pliers, is it worth buying a pair for this one job? also the bolt that holds on the pully has no head for a tool, is the best way to get the bolt out using a grinder to grind a place for a large flat head screwdriver?

[@oldradio16]

I have not been able to get the bolt out of the compressor yet...but haven't had much time to work on it yet

[@deasttn]

You will need snap ring pliers. Some places have them in a cheap too bin.

[@radicalvictor]

Compressor kicks in sometimes and sometimes not any idea why

[@oldradio16]

I would suspect low pressure in the system, should be able to have it atlest checked about anywhere without much problem.

[@gregoriodimaandaljr3359]

are yours fixed already? I am having the same issue. Some ac (cold) is working and sometimes not.

[@rubenchavez9086]

Its easy never did mechanic work and changed it myself

[@houstonmarshall5046]

I have a 2006 Nissan Altima It blowing a 10 amp fuse Everytime I start the compressor why?

[@deasttn]

@@houstonmarshall5046 your clutch bearing may have wobbled so much that it caused an electrical short near the electro magnet.
