Faulty Air Conditioning in a 2000 Nissan Pulsar N16

I've been pulling my hair out with my car at the moment. She is losing power intermittently. First I thought maybe it was the fuel filter or a petrol problem, as it only happens every now and then, like going up steep inclines or turning into another road, but not all the time. We have changed the gear box oil. I don't know whether it was just coincidence, but the motor in the air conditioning has been making a funny noise and it did stop working until my other half changed one of the fuses in it. We drove this morning without using the air conditioning and the car seemed to drive alot better. Would a faulty air conditioner have anything to do with the motor losing power like that?

    Thanks Fyrebyrd,



    It really did help knowing that I wasn't just imagining things, but I am going to test it again tonight on my way home. I won't use the air conditioner, even though its probably going to steaming hot out there lol but I will post another comment tomorrow and let you know if it was just coincidental or if it is the air conditioner causing the problem. Hey it might help someone else on here who is going through the same problem :D thanks for your help!

    I have a 1998 Nissan Pulsar Sedan and the Air Conditioning is cutting in and out. Each time I lose power and it is like the car is missing. If I don't run the Air Con the car runs fine. I haven't solved the problem yet.

It's quite possible that your A/C compressor is locking up, thereby causing excessive load on the engine.(translates into lack of power to drive wheels) Typically there are signs, such as the noises you heard, or a slipping or thrown belt. If the compressor is locking up, being belt driven it will draw excess power from the engine. It's also possible that the compressor clutch in conjunction with compressor is going bad as well (both are usually related). That would cause excessive amperage to be drawn through the circuit, thereby blowing the fuse. Ultimately, it sounds like you have figured out your own problem, but I hope what I've posted helps.

The air con on my 2000 N16 pulsar keeps cutting out...sometimes it works fine but other times the light wont come on on the button and the air doesnt cool when this happens.is it a loose connection?


It could be a loose connection or bad section of the HVAC module, yes. If it checks out I would check the pressure in the high/low side which could be tripping the switches to cut a/c operation.
