I just bought a 2010 Versa 1.8S HB manual transmission. I am having some problems with the air conditioner.
It looks like the air conditioner works intermittently. When the engine is running, but the car is stopping at neutral, I push the A/C button to turn in on. After some hissing and other noises typical to a compressor starting up, it looks like the compressor disengages after about 30 seconds. Then, it turns on again after 6-7 seconds. From then on, it works intermittently for about 10-11 seconds with 6-7 second intervals. (The A/C light stays on during the whole time.)
I can tell that from the clicking noise I hear every time the compressor engages and disengages, also, can see a little ripple at the rpm. When the hood is open, you can clearly hear the noise every 10+7 seconds.
The effect is more pronounced when I'm driving. At constant speed, every time the the compressor engages, I can hear a very clear start-up noise from the passenger side. And this happens a few times per minute. Very annoying.
Apart from this, there is a load humming noise when driving with the A/C on. Same problem/noise is present when the A/C light is off but the fan is switched to defrost.
Any ideas on this? Has anybody experienced similar problems? It is hot outside but I'm scared to turn on the A/C for the fear that it will wear out.
I'm going to take it to service next week.
