How does a clutch switch shrink?
Half an hour to retrofit a cruise control lever and lower cowl, followed by and hour and a half upside-down in the footwell trying to understand why the clutch switch imagines the pedal has been depressed.
To play this game you need to be fit, young and flexible, and capable of inverted use. I am not.
It took me half the time to figure out how to remove the poxy switch. The answer, which seems to be unrecorded anywhere else on the internet, is to twist it 90degrees. It will then lift out.
But why doesn't it work? A multimeter shows it's fine. There is no external sign of wear at all, but the plunger seems to be about 4mm too short. So when the pedal is at its normal height, the plunger isn't pressed in and the switch thinks I have my size 10 on the pedal.
There is no sign of wear anywhere in the pedal mechanism, nothing bent, so it appears the only explanation is that the plastic switch has shrunk. Eh?
I've stuck a small magnet on the plate that depresses the plunger, to take up the slack. So for now it works. But I'd love to know what the hell has gone on here, and whether a new switch would solve the problem? I did think about taking it apart to see if there was internal wear I could pad out, but I need to use the car and I am sure it will be filled with ping****its.
