NYC Winter Storm - 2014 370z wont start
 

Hey guys, so its pretty cold over here tonight feels like 10F, was outside taking the mountain of snow off my 370z, then turned the car on just to crank up the heat (didnt turn the engine on) had it on full blast and then went back outside to take off more snow

after about 7-10 mins went back in the car to warm myself up so i turned the heat up more to about 90 degrees inside the car and turned on the seat heaters

after a few mins i noticed the heater stopped working so i thought that was weird so I turned it off and tried to start the car and it wouldnt start / tried a few times didnt start

never had this happen before, is it just cause its too cold and covered in frozen snow or something else?

when i turn it off completely i could still get it to turn on and when it first turns on you can hear the heater working again but then it cuts out after a couple seconds / car stays on just heater wont stay on and engine doesnt start

any ideas? im just hoping by tmrw it kind of just fixes itself up lol but thats probably unlikely :confused:

Wait, how do you turn the heat on with the engine off ?

It's probably your battery.

Ps- this snow was crazyyy

I just double tap the engine start button without pressing the brakes and the heater works then

and yeah hopefully a jump start tmrw will fix it and then I'll go check if I should replace the battery or not

and dudeee... NY weather is ridiculous lol one day its 60 degrees in feb then next day its like a frozen antarctica

Umm dude heat aint gonna work if the engine is off! Engine needs to warm for heat to work, what are you doing? If i understand u correctly you smoked your battery

I'm not sure why you did what you did, but like everyone
is saying, sounds like your battery my friend.

Interesting, clearly I'm a car noob but I've never had an issue with turning on the heat in ACC mode (just found out thats what its called) not sure if the engine is somewhat on for 370z in this mode or not

but yeah will check what it does tmrw if anything will jump start it / after i jump start it, is there an easy way to know if i need to replace the battery by looking at the voltage gauge or something or do i have to go to autozone?

thanks for the help guys!

I'm sorry but i can't imagine how it must of been like, turning on the heat while the engine is ice cold. Didn't you realize that it was just blowing cold air?

I don't think there's a single ICE car that has an electric heater lol:pics:

LOL thats the weird part like when i first turned it on i left my car immediately to go clean it outside so it probably was cold then but when i got back in, it was very warm inside so idk man lol

Wow.. new threshold

Wow is right......

:wtf2:

Wait. What?

:facepalm:

Don't be soooo closed minded guys!
There's always something new to learn :bowrofl:
Has anyone ever tried it? :bowrofl:

OK. A couple of things.
Your battery may not be fried, just dead. It was sitting for a while in cold weather, which weakens the charge, and then you ran the fan motor and all the other electronics for a while and it just ran out of power.
Don't leave it that way any longer than necessary. Leaving a dead battery sitting will kill its ability to hold a charge. Jump it off and run it or drive it for about 20 minutes to charge it up, and then either run it for 7 minutes or so every couple of days, or put an automatic charger on it to keep it topped off. That's the battery.
A car, or more specifically, our cars, require the engine to be started to generate the heat for the heater. Our heaters are water-to-air heat exchangers using hot water from the engine cooling system for a heat source.
The "warmer" effect you are feeling when you sit in the car after working in the cold is just the absence of the breeze blowing the skin-warmed air from off of your face. You would get the same effect with out the fan blowing. It would probably even be more pronounced. Heat also builds up inside your clothes, but goes unknoticed until you stop to "warm up". Same principle when you go in the house. It usually gets almost too warm at first, until your body adjusts to the temp change.
If you have a chance, pick up a basic automotive text book, (Try Amazon) and learn a little about the systems that make cars do what they do. It will also help keep you from being ripped off at a mechanics shop.
Good luck!

After you jump start the car and run it until it charges up, you can kill it and wait about an hour. If it starts then, you're probably good.
If your battery has removable caps over the cells, you can buy a specific gravity tester at the auto parts store to test the battery. Follow the instructions on the package for the test ON A FULLY CHARGED BATTERY. Be careful. You're dealing with a very strong acid. It will eat you and any part of your car it comes in contact with. This is basically a turkey baster with a guage built into in.

Same OP. Good luck lol.

Thanks man, that was super helpful, learned a ton!

And LMAO yep i've had some next level stupid moments with this car but eyyyy sometimes failures are the best lessons, i def won't be forgetting this stuff anytime soon :rofl2:


UPDATE: GOT LUCKY it just turned on without any issues, didnt even need a jump... but lesson learned, thanks for the help guys!

OK, so you killed ur battery by using your electronic seat warmer.....Ventilation heat comes from the engine.


I don't understand how this thread got to two pages.
