heater blower problems

[Syus]

Hi!

I'm having major problems with my heater blower and the resistor... well actually i don't exactly know what's wrong so i ask for help

My problem is following
my heater blower works on 1-4, but the problem is that on 1-3 the resisotrs cut the power to the blower after some time
I inspected the resistors pac and the wires get glowing red
I also tried to replace the resistors pack with another one and it did the same

So i decided to take out the blower and inspect it
I used WD40 to clean the electrial stuf of it so now its completely clean

i asembeld it back together and the problem is still there

I got clueless after that because i don't know anymore for what to look at


please help
i don't want to spend a whole fortune on car electricans


thanks for help

i would help but i cant. i have more or less the same problem for a few weeks but i have not got to fixing it yet.

an electrician said it could be the circuit board? try replacing that? or testing it.
have you checked the motor runs freely?

i am going to tackle mine at the weekend, if i can pass on any advice i will send you it.

good luck

found the problem..
the resistors pack wasnt in the slot in the plastic of the ventilation tubes so it wasn't cooled...

stupid...

now it works all like charm
