Hi all,
The blower on my 306 XS (phase 3) has decided it doesn't want to work this morning. There is no fan noise whatsoever regardless of what position the dial is in. Also, the fan normally quietly whirrs when in the off position (apparently normal behaviour) but even this isn't happening.
The AC button still lights up and the AC unit kicks in, also the rear heated window lights up and functions normally. I mention both of these as they are apparently connected to the blower in terms of fuse/relay being used. Regardless of this I have swapped fuses/relays that I believe to be related to the blower with no change.
So would I be right in saying 4 options to check???
1. Resistor - I've seen a lot of people say this is the first thing to consider after checking the fuses/relays. However, I came across someone who said their blower was always on full whack and it was because of a failed resistor. Kind of made sense that if the resistor fails, there is no... er... resistance so it gets full power! Maybe suggests this will waste my time looking into but happy to be corrected? If I were to check, am I right in thinking the resistor is attached to the blower motor on my phase 3?
2. Blower motor - No noise whatsoever so maybe the motor has died?
3. Switch - I guess this would be the thing to check if the motor/resistor are deemed good?
4. Short - A similar historic thread mentioned there was some kind of wire behind the stereo or clock that was shorting out and caused the motor to stop working. Just wondering if anyone else has heard about this or thinks it may be plausable? Surely there aren't lose wires hanging around behind the centre console? I will however add to the mix that my clock.temp dsiplay quite often stays in the dim mode and needs a friendly thump to make it light up. It has been like that for well over a year so surely unrelated but maybe my thumping has gradually caused a further issue?
Please help.... it's getting cold!!!
