Honda Jazz Mk3 2015 - 2020 / Re: Honda Jazz Mk3 Heater on Ex-Navi
« Last post by Toptek on Today at 12:37:09 PM »
I'm not a big lover of the touch screen, much prefer a few knobs :) and it doesn't seem to shift much air compared to other cars I've owned.
However, I tend to mostly set it to "auto" and let it do its thing. In the colder months, it waits for the heating to warm up to have something warm to circulate, therefore, you can increase the fan speed manually and eventually it will get warm enough for you to press the auto icon. I have to do this as ours suffers a lot from condensation in the winter.
Also, I find in summer I tend to increase the fan speed if I'm feeling particularly warmer than what the car's system is deciding to do, then again pop it back on auto.
It would appear most people say to leave it mostly on auto to ensure the AC system seals are lubricated.

Yes its not unusual to take 5 minutes to get useful cabin  heat when starting  a car from cold.

On cars with an internal combustion engine (petrol or diesel)  the engine is kept cool by circulating coolant (a mixture of water and antifreeze) around the engine   and then cooling it by passing it through a radiator at the front of the car.  Engines work best  when hot - with the coolant at around boiling point. (Its best drive more gently until the engine has reached its operating  temperature. There is normally a blue light telling you the engine is cold. Take it easy until this light  goes out) )   If the air passing through the cooling radiator is  cold it can take longer to warm up.  There is normally a thermostat  in the system that stops the coolant circulating until the engine is warm , so it heats up quicker. 

For cabin heating there is a second small radiator  behind the dashboard.   When you switch on heating  a valve is opened so some of the engine coolant passes through this heater radiator and it gets hot.When you adjust the heating level it adjusts the rate of flow of hot coolant  (which may not yet be hot  ;) )
Air is directed to the cabin and heats up as it passes through this little hot radiator.  Some comes in as you drive along, or you can boost the amount of air by using the fan.     You can also distribute the hot air where you need it most , such as to a frosty windscreen , or your feet  or a bit of both.  You may need to adjust air flow , fan speed etc to suit your needs and comfort as the car warms up.
A car with climate control  can adjust heating and air distribution automatically  using electronics  . Or you can set things manually. Your system can also control and cool temperature automatically (or manually) by using air conditioning.

Put in very simple terms Airconditioning uses a  second separate  system of  radiators to cool air below the ambient air temperature.   

There is quite a bit to learn to have full control of heating and cooling.     Its probably in the drivers handbook which you can download free from Honda as a pdf

About 5mins is normal as the engine has to get some heat into it before it opens the heater valve.
Colder temps take a bit longer.

What I normally do is set the temp to cold for about 3-4 mins first so engine gets warmer a bit quicker and then turn heating on.  Seems to work better that way for me.

I had a MK1 Jazz before and sold it to a friend.  The car has currently just ticked over 201k and so far all it's needed are normal wear and tear items and a clutch at 165k.

Reguler oil changes are the key to keeping these cars going I think.

With our car, that would be filed under patina and evidence of a life well lived.  ;D

That said, I know these things can annoy once you've noticed them. Maybe replace with a cheap used part? Ebay would be my choice for searching.

Our loyal little Jazz hit 144,444 miles the other day.  8) The car has never broken down, only ever needed servicing and still runs really well using no oil between services. Brilliant little motors.

Next stop, 150k! I've total confidence he'll fly past that milestone.

Your car has fog lamps in the lower bumper. On the MK2 Jazz in the UK, only the posh models got those so I'm guessing you've got the SE? Sport models come with side skirts IIRC. You could phone your local dealer with the VIN number and ask them?

I would be in touch with professional vehicle dismantlers and breakers such as Synetiq, Reclamat and Silverlake. Give them a call with your VIN no and see what they have.

Ebay cars breaking is another good option. Breakers list the cars and you contact them for the part you need. Photos will be provided and parts come with a warranty from decent firms.

Honda Jazz Mk3 2015 - 2020 / Honda Jazz Mk3 Heater on Ex-Navi
« Last post by ramaka on Today at 11:07:20 AM »
I am a new driver with first car as Honda Jazz MK3 Ex-Navi. I don't know how heaters works in Cars hence want to know how much time does it normally takes for the heater to start blowing warm air when the outside temperature is in the range of 5-10 degrees. What I noticed is, it start blowing warm air after 5-10 minutes of driving, is that normal?

After staring the car I set the temperature to hi and climate control to auto mode, and then once after 5-10 minutes when it starts to blow the warm air I set the temperature back to 20 degrees or so. Am I doing rights here and Am I using the heating system correctly?

Also can someone please explain the mechanics behind the functioning of Heater in general.
