Nissan 1.5 petrol cutting out when heater is on??

[eltax91]

Hi all

Just a brief one. My MiL has a 1.5 petrol powered Almera, 53 plate. She has had an issue yesterday and today whereby the car just stops running! She drives 1 mile to work and back, twice a day. It cuts out just as the heaters turn warm, no warning, just an engine cut-out.

If she runs the car for under mile and turns the heaters OFF, the car is freezing bloody cold, but it has goneon to run for 10 miles + with the heaters of.. Turn the heaters on, and within a mile it cuts out...

Any of you Nissan whizzes out there any clue what might be happening?

Cheers all and merry christmas

Battery/alternator issues?

+1 and a mile to work...... Walk..or Cycle...save putting cash in the governments pocket, save you a packet PLUS....it will help towards keeping the price of fuel down if less of us use it......next week many of us are off work,....if we all stay home instead of running to the so called "sales" that never are.........more fuel sloshing about = lower prices to shift it.....same as saturday or sunday at home ...parked up... you know you want to...

Cheers for the lecture! Not my mileage and I don't need to justify anything to you, but she is a teacher, and has to take the car to work as she is on the list of teachers which ferry the kids to hospital when needed or home when mummy or daddy can't make it to pick the kids up.

What a pointless,useless most un-PH-like post, from the man with the Mazda bongo friendlee What if the mile to work in along a dual carriageway with no pavement?

to the OP- when you say it cuts out when the heater is on, do you mean when you switch the heater on, or when the car has got up to temperature? Do other electrical items make it cut out? Can you restart it when it cuts out?
Wonder if it is a themostat problem indicating the car is overheating? Does the temp gauge work on the dash?
Air intakes free of leaves/snow?

Thanks for the useful response.

The car runs up to temp fine. Will work no problem. Unless the heater is on. As soon as the heater goes on, it cuts out within one minute. It will restart no bother! Turn heater off and all ok. Leave it on and it cuts out!

Not had time to test other electronics yet.

Perhaps something to do with the temperature sensor? The heater goes on, car thinks it's too hot and goes into some kind of safety mode?

I'm definitely not a mechanic so this may be a totally useless post!

I imagine the heater is a red herring. I can't imagine how the two are linked.

No EML on?

[odyssey2200]

when you say heater to you mean the fan or the temp control?

[sly fox]

Just a thought- when you say heater, do you actually mean the Air conditioning?
AC Compressors consume a huge electrical load when engaging, wonder if this is what kicks in and causes car to cut out?
Is the alternator original?

if it's the heater motor for the in car heating the fan motor may be siezing and causing the ign connector to overheat? happend pm older cars ?

I would be tempted to connect a small value ceramic disc capacitor across the heater motor just in case it has become electrically 'noisy' (for example due to worn brushes) and is upsetting the ECU. (If it has become noisy, you'll most likely hear a lot of interference if you tune the radio to AM with it running).
