Canada? Gotta get you set up cuz it is getting cold and you gotta have that heat!
OK, so you are educated on how the HVAC fans typically work as you stated about the resistor.
i totally agree! its even harder to work on u<r car outside in this weather!
So, how many miles?
i just dont know if i need to change the resistor or the blower^
85000 km, so approx 50 000 miles!!!
Well, here is the thing, you hooked the battery up to the blower directly and the blower works fine? No noises? Spins freely? BUT the wires got super hot right?
so hot they almost melted!!!!
OK, that is bad and the blower motor is drawing way too much current. It has to be replaced regardless. I am wondering how big of a fuse you have for the blower motor? The excess current probably damaged the resistor as it could have happenned on all speeds hence losing all speeds.
WOW! is it a larger (physical) 40 amp or just a standard blade fuse?
larger, mid size, never seen these types of fuses, in with, it would be loke adding 4 regular type fusing next to one another!!!!
It stll does not justify the wires almost melting.
sorry, bad typing,what i meant to say in width, !!
does the wire size matter
Sure, bigger wire can handle larger currents
the wires i used were from a cheap tester, i had nothing else,
Hang on, so explain to me how you jumped it?
the motor is 600 bucks in my area, oh and the resistor is 100$, i just want to make sure im not changing parts for nothing!
OK, sure, thats alot. Which wires were getting hot? The cheap wires you used to jump it or the wires on the motor?
well, i used a battery from my father-in-laws boat im storing in my garage for him, removed the blower from the car, used the wires from a tester i bought from Canadian Tire(auto zone for you guys!! :)) , motor worked right away with no noise, but the wires werent happy!
So the cheap wires got hot right?
The thing that got me thinking was the 40 amp fuse
Thank God we ask questions
if u know speaker wires, they were about 16 gauges
HOLY God! 40 amps going through tha! Maybe 20 but...
Well I think the blower motor will survive!
so do u think i still need to change the blower, i was initially thinking of only changing the resistor, but if that blows, there goes 100$
oh! so only change the resistor!
No, the blower sounds like a beast. They give that circuit factory protection up to 40 amps! That is a powerful motor.
I would only replace the resistor. There is still a possibility of the switch but the resistor is more common.
the switch on the dasboard
With the fan speed control. less likely though
ok, so if the new resistor blows, which i hope doesnt, sure I go for the blower or the switch
isnt it weird thought that all speeds would fail if its the resistor
I don't think it will BUT that blower is $600! Before I would commit to that, I would have an motor shop check it out.
No high speed?
before changing the resistor
no speed at all!
That resistor is electronic though. I would consider having a motor shop check it out. Good piece of mind and a fraction of $600. Just don't tell them how much new is
Motor shop checking out the motor not the resistor
yup! thanks for ur help
And the resistor is electronic so all speeds could possibly fail
Is there anything else I can help you with?
no, all is good, thanks
If not, can you please rate my assistance in a positive manner as this is the only way I will receive credit, thanks and thanks for letting me help you.
