    Any advice appreciated.
    Last week my fans briefly started blowing hot air at me regardless of the temperature setting. It only happened once so I'm hoping its not the start of something expensive. Anyway, I took the glovebox off this morning and located the relevant motors, loosened them off, dusted down the linkages with a paintbrush, gave the linkages a good jiggle about, squirted with WD40 and reconnected. While I was in there I started the car up and started playing with the controls to see the mechanisms moving. The Green one didn't seem to move regardless of the temperature or fan speed selected. Is this normal? I should say that I didn't run the car up to running temperature.

    Make sure you do the motor on the drivers side as well, lots of people forget this one, especially as it's a ***** to get to if it needs replacing...

    Cheers for that, didn't realise there was another. Pretty obvious when you think about it having dual climate control!

    Ba-jesus you weren't wrong about getting to it! Not a job for anyone that is a bit impatient and has sausage fingers.
