Fault with heater?

Post by evoke » Wed Oct 30, 2013 10:23 pm

^ Climate control is different to air-con in cars. With climate control the air vents and temperature is controlled for you. The car operates the heater and the air-con compressor as required to maintain cabin air temperature and quality at the correct level, and directs air through vents automatically.To use climate control optimally, you should have all the air vents open and set the climate control to 'Auto' (in most cars that i've had over the last 15 years or so).It's also important not to have air-recirculate mode operating whilst the climate control is in the Auto mode (some cars will engage the air-recirculate mode automatically to get the cabin up to temperature quickly or if they have sensors to 'smell' the air and detect various odours.

So as I understand it the car always takes in air from outside, even when the heater is set to recirculate. Is that right? If so it would go a long way to explaining the problems I have had trying to get the car up to temperature and the rear side windows free of ice in cold weather. I was on the verge of selling the car last winter because of this, and have been wondering what to do about it in the coming winter. Maybe I'll rig up a flap of my own to block the vent.

I have had my second juke for four months and since purchase have been plagued by heater problems, which were not apparent on my first Juke. The issues seem very similar to those described in that even when i turn off all heating controls (air-con, climate control) that hot or cold air continues to blow. This is exacerbated by the fact that you can not close the central vents. A further problem is that the you can only have hot or cold air (nothing in between). When i switch my car on (even with the heating/air con controls switched off I immediately get the temperature that was set the last time i drove. I have now had it in the garage three times and have been told that this is the design and that all cars have air flow through the sensor grills - which i can accept but i would expect this to be the temperature of the air outside, and to be honest I have been testing it out in friend's cars of different makes and models and none appear to have the same issues. This certainly did not happen in my last Juke. The problem with the only having hot/cold and no incremental temperature increase is also the case when the air con/climate control is on. I have tried setting it on auto, recirculation - in fact i have tried any which way to no avail. I have been in touch with nissan customer service and was advised that this is the first complaint that they have received in relation to this and yet i have researched it on the web and this forum and it certainly doesnt appear to be an isolated case. In four months i have gone from a happy contented nissan Juke owner to one who is extremely dissatisfied and unhappy.

I understand how frustrating that can be as my Juke is now constantly blowing really cold air! Did you manage to get it resolved in the end?

Hi, just to add to possible solutions: -just purchased a juke and once the sun had set realised things where a bit chilly!... had a look the next morning and the wire to the actuator which controls the flow of hot air had been unplugged (possibly when serviced as part of the cabin filter replacement process - remove the glove box tray).The cable is terminated with a white plug and can be found underneath the glove box to the right hand side closest to the center console (looking up under the dash from the foot well) to the right of a white polystyrene block. In our case it was hanging loose so just plugged it back in and now we have heating in the cabin again!.. panic overthe nice part was that no screws or dashboard parts needed to be removed!Thanks again to the people who posted here, it really helped me find where everything was located in a strange new car and fix it without spending a fortune!

Hi, just wanted to say thanks to Fluffkat for the tip. My Tekna was in for a service during the week and I noticed today that it was only blowing cold air out, even with the AC cranked up to 30degC. Going on holiday in it first thing tomorrow morning so needed it sorting sharpish (who knows what the British weather will bring us next week!).

I popped the air filter out (clips), dropped the glovebox (3 screws above, 4 below) and there was the little white plug dangling at the back. Plugged it back in and warm air returned. Job done. Nice work chaps 8-)

Another thanks for this tip as had this fault with new Juke picked up at the weekend, seems the unplugging of this wire is common on cabin filter replacement during service
Dropped the glove box and there was the offending white plug hanging free
