#1 of 1 Loud AC compressor 2005 G35 Sedan by denn77 Sep 10, 2009 (12:08 am)
I've taken my G35 to the dealer a few times about my loud a/c compressor already. The first time they replaced the compressor but the noise never went away. Now they're saying it's normal even though the sound is quite loud. It sounds like rattling when I accelerate the engine to approximately 3k RPM with the fan speed and temperature settings at max. The only way to make the sound go away is to vent (release) some of the r134a from the system but then I loose cooling efficiency. Still under factory warranty as I have 57k miles. I've uploaded a video of it. http://www.youtube.com/watch?v=YhcuCL32BEQ It sounds kind of like a lawn mower engine and goes away as soon as the A/C is turned off. I've taken the car to 4 different dealers now, all say it's normal. I don't believe that for a second. I was wondering if anyone has the same problem and/or a solution? Thanks!
