    140.jpg hi all i thought i would share my find as i don't think its common knowledge,
    the heater blower stopped working on my 05 dci almera van i narrowed the problem down to the heater resistor
    i got a replacement in a scrapyard for £25 swapped it over and the blower worked again.

    my curiosity got the better of me i had to take my old resistor apart to try find out what was wrong with it
    as expected i couldn't find any obvious issues, i decided to plug it back into the car for further testing i was using a multimeter to check for power in/out and i accidently bridged 2 contacts with the multimeter and amazingly the blower worked, i soldered a spare ecu pin to bridge the 2 contacts. it has been a year now since i did the mod and unbelievably the blower still works perfect in all modes for any length of time,


    i will put a pic up to show this easy fix, regards frank
    .edit.
    you can see top left where i soldered on a link from the diode to the pin,

    happy to share this hope it helps someone out

    Been covered a few times, I know when it happened on my n15 it was pretty obvious where it had blown, dollop of solder and it was fine x x

    If it's damaged do the blowers stop working at certain speeds? Mine works on all speeds but the blower is very weak, highest setting is like the lowest on other cars.

    Motor could be dying or the pollen filters could be clogged up.

    Clean vs dirty

    this is not the same type resistor, the resistor i'm talking about is located in the drivers side left of the clutch pedal held in place with 2 bolts i'll get some pics up soon

    I have the same problem, the motor factors keep supplying me with those white filters, and I keep telling them mine are brown :D

    Me too the same problem and I cant find it. I looked under the glove box and left of clutch. Also my pollen filter was in bad shape and I just took it out for now. Should be able to start if I fix it without the filter?

    Looking at the wiring diagram, it looks like what has blown in most cases is the fusible link on the blower resistor board, which I suppose is supposed to protect the blower motor from overload. The thing is, I'm not sure why it's even there, since there are anyways two parallel 15 amp fuses in series with the blower resistor which provide protection for the blower motor. Just an over cautious design? At least that's how it's setup on the N15.
