Hi

As above, a lurker previously but now time to introduce myself. Nissans have been the family conveyances for many years, and the Note comes in with Mrs JSP who's had her Intense Blue '57 plate E11 for about five years now. It was a replacement for her old K11 Micra which she'd had from new in 1997, but which eventually got beyond saving after about 16 years of use. The Note's been a pretty reasonable car - a couple of new springs, a rear wheel hub and rplacement a couple of months ago of the original battery. A couple of issues remain long-term unresolved, but are not treated as urgent. First the aircon refuses to hold a charge and second, a rather horrible noise when starting the car from cold, which is again, I suspect, aircon-connected. 80k or so on the clock and around 43mpg around town from the 1.4 petrol motor. A run will push it up to around 50mpg. I certainly enjoy driving it - in fact, I think I drive it more than her.
I've also been driving Nissans for years. A P10 way back (a company car, and actually not my favourite) followed by a 1.6 P11 which I eventually bought from the company. A lovely driver's car, just lacking on power a bit. One or two issues with it led me to move on to my present car - a 2003 P12 2.0 which I've been running since 2006. Still good, but each year a little more needs doing but it'll stay as long as is sensible. The Renault influence on reliability is sadly evident in some respects.
When one or other car bites the dust, it'll be down to one car (we're both in our 70s now) at some stage. If the Note outlasts the Primera then fine, I'm happy with that.
One thing's for sure, though - the replacement will not be a Nissan.

Hi JSP welcome to the forum.
I'm not much on the engine noise side of things but to me the air con sounds like it has a pinhole leaf somewhere. Get to a reputable air con specialist and the will add a dye to see where the leak is and get it sorted for you. Or you could just leace it and not bother with air con at all.
If the air con was noisy at start up then i assume that it is already turned on or it would not engage the clutch on the compressor.If so try starting with it turned off.

Thanks, Sineu - I've been messing around with cars for 50+ years and I know plenty about aircon leaks! It's simply that it's not been a particular issue (I'd just as soon drive with my window down) but this past couple of summers have rather reinforced the need for it to be working. I'll get round to it.
As for the noise, it happens whether the aircon has been left switched on or not. In fact, the only time it's switched on when starting the car is if previously I have selected the de-mist positions on the heater and switched off the aircon - obviously, as it's not operative - but left the air distribution in the screen position so that when subsequently starting the car the default position is, of course, on comes the aircon. Or not, in my case!
Anyway, thanks again.

Welcome


My aircon gave up years ago too, at about 3000 hours running. It doesn't leak when tested with vacuum or pressure, but won't hold gas more than a day. I think the expansion jet is clogged, and the over pressure blows it out of the pump seals. With no gas the clutch never engages, whether the light is on or not, so it won't be the aircon making your noise- but it could be the bearing in the pump pulley, or the idler.



Mine makes a dreadful rattling noise underneath when the weather is cold, I think it is something broken inside the exhaust pipe, I can't find anything on the outside that could rattle.

If it makes a noise when just starting up, it could be the bendix spring, dirt in the splines. not pushing the starter gear out of mesh with the flywheel gearing once the motor has started. Nothing to do with the aircon clutch sound.
