2012 SV- 108k


No previous problems with the A/C. A few weeks back, I was passing a few cars on a 2 lane highway, didn't see an oncoming car, and had to really drop the hammer to get around in time. Right after that, the A/C stopped blowing cold air and hasn't worked since. I immediately checked the fuses in the cluster (only 1 10amp which I thought was weird), all fuses good. The compressor doesn't engage at all. Not sure about the cooling fans that others have mentioned. Am I missing something simple here? I have looked and the compressor is still plugged in, but haven't checked the voltage. Any ideas as to why this might happen after running high rpms. Bad compressor? Clutch? I really would like to avoid the dealership or shop if I can. $$$


Thanks!

 

I have seen several clutch coil failures in Maximas and Altimas lately.

I would apply 12v directly to the compressor and see if the clutch engages.
To do this with the engine off is easier/better. It is a little trouble getting to the connector, but this would be a good test to rule out this component.

Based on my experience, this is probably the trouble. Just a coincidence that it happened after full throttle application though.

Of course if you are still under warranty this would qualify as a claim.

 

I am going through the exact same thing! this car has been good, no major problems until now.
I took it to a shop and they are saying that its a ground problem. my nephew is a certified
mechanic and he says its a problem with the clutch. if anyone finds the problem please post and let everyone know as I will do if I find out what the cause is for not working properly.
thank much,

I've had my blower lower its speed and come back up on its own randomly maybe less than 5 times since March 2014. Any clue what that's about?
