just a quick question boys.... when you turn on the heater of your car, from where does the air get into... im telling you this cause its the second time my blower shorts. In winter when i had the heater on in the snow, some snow would come through the blower and same thing happens in a car wash... any ideas?

 

lol snow through the heater, thats fantastic. The heat supplied from the heater is usally taken from the engine bay. Hence when you start the car and its cold, you turn the heater on and its still cold till the car warms up. Also if your car is over heating and you turn on the heater, it will help dissapate some of the heat. (people tend to do this while auto-xing or on a long *** drive to say, arizona)

 

so why is it when i turn on the heater i get snow in the car? and when i go to a car wash i get water in the car when i turn it up?

 

The air that is blown by the heater gets in by the bottom of the windshield:
if you look at where the wipers rest, there is a plastic piece that spans the area between the bottom of the windshield and the engine bay/firewall, it's mostly hidden when the hood is down however. along it there are slots through the plastic which are where the air goes in.

If you are getting snow in the car, it's probably because there is snow there (it's a hard part of the car to clean).

By the way, the reason it is placed there is because aerodynamically, when the car is moving, air accumulates and rotates at the base of the windshield before moving up and back. having the air vents there allows fresh air in the car without it having to be "sucked" in by the heating system - that's why when the fan in a car is off, there is still a bit of air circulating.

 

i know exactly what your talking about man. the air coming into the car when its off too... but thing is i dont understand why my motor keeps dying... this is the 2nd time i change the blower... i mean if im in a car wash and i turn on the fan, it will go through the blower... is that dangerous? and could it cause a short??

p.s. i guess you read this on the honda-tech board before you got to reply on ottawaprelude.ca

thanks for your time though

 

lol yeah i dont check tech in ottawaprelude that often...i thought your name seemed familiar

i dont know why it would kill your motor... what gen is your car? 5th?
water shouldn't be getting in there. did you replace the motor yourself or was it done elsewhere?

water shouldn't be getting into the fan, yes hypothetically it could create a short. is water leaking on the passenger side footwell sometimes?

 

its a 4th gen and yes thats where it leaks from... the right passenger side... the snow doesnt come out of the vents.. it comes out of there...

the motor was not replaced by me.. it was somewhere else

 

Id say you have a direct leak in your firewall close to the ground. If its coming from the passenger side and NOT the vents, id say pull up your carpet and start lookin fer holes If none are visable try opening your hood and looking underneath the fusebox, or the rest of that side. Maybe a rubber housing for a harness or some type of wireing wasnt put back. Hope that helps some.
