i-MiEV A/C ticking sound

Only when A/C is on, is this normal?
Check out this video, the ticking varies in speed.

Mine doesn't make the ticking (US spec). May need to hear from others before calling the dealer.

I was just pre-cooling our iMiev yesterday, and noticed something similar, it almost sounds like a fan that's just gone out of balance a little. But, it could just be "normal", not sure.

That's when I first noticed it too, whilst pre-cooling.

That's very loud. It almost sounds like you have a gas engine in there. You must have a Euro-spec i-MiEV, the NA spec i-MiEVs have the mitsubishi badge on the hood.

Yes, sounds like there's a small petrol engine in there lol! And yes, it is a Euro-spec i-MiEV.
Called the dealer today, the i-MIEV is scheduled for a brake system vacuum pump replacement in about two weeks so they'll check the A/C at the same time.

My new (though a 5/12 build) SE Premium has a similar issue. :? The air conditioning compressor is louder than the one in my ES was, and also noisier than the compressor in LeeC's ES with CHAdeMO. During full air conditioning use it has an audible piston compressor sound (about as loud as the vacuum pump in a Focus EV, not quite as loud as the vacuum pump in a Volt). It also seems to be on a VFD or some sort of stepped pwm controller. When I did my first CHAdeMO charge last night, the compressor frequently cycled up and down, through perhaps 5 power increments, and much louder than for regular air conditioning use. It still wasn't quite as loud as your video made it seem, more of a lower-pitched drumming sound.
- btw, I also have noticed that it appears to have a different vacuum pump, though my 10/11-built ES was not subject to the recall.
- I have not finished reviewing all documentation proving that the recalls have been addressed on this car.
