After obtaining our new clubsport unfortunately we had a issue with climate control fan speed on lower settings,
only high speed was working due to high speed running of a relay & (AUTO) 1-2-3 running on a speed resistor...

another give away sign is a small x in the corner of display

After getting a few quotes from holden I was quite shocked and turned to auto electrician's which I must say where more forgiving at $200 but still $200 lol replacement part is roughly 60 -90 dollars compared where you shop

soooooo here a top tip..... it seems that there is a connection on speed resistor between cooling fins and electronic board this is bent away from main body to prevent interference which creates tension on the connection and breaks over time due to potholes & what have you, A touch of solder and 30 min later 5c worth of solder and working like a dream

here is a simple run down I will include photos when I check the senator's unit

1:Open glove box & remove the 2 rubber clips
2:pull glovebox down and it should unclip itself & allow removal
3:Now you should see a plug with 3 wires running to a white oval shaped unit with 2 screws entering hvac.
4:Disconect wiring plug undo 2 screws
5:Remove speed resistor and visually check the wire-band for connection very obvious!!!!
6: if broken connection re-solder if not double check fuse beside this
7: Reassemble and enjoy & wonder why you never did this earlier


enjoy guys hope this helps at least one other person it saved me heaps....

Back in the day they used to burn out then use to stuff up as water used to sit on them and the board so we used to modify them by mounting them upside down so the water didnt sit on the elc board.
But it seems after all these years there still stuffing up.Never had a problem with my car.lol.

With these they are covered with open bottom section so water does not sit on board, not to say that condensation couldn't play a part in making it brittle...
But trying to have a conversation with high speed on when its 40 degrees lol

It doesnt mater as its where they are.Their in the box where all the condensation is where mine is out in the planum and high and dry.
34 years and still going.lol.

That's a good innings lol

When you are a mechanic you stay with the cars that you dont have to work on much and that means their long in the tooth as well.lol.
