Spoiler related issue...'spoiler control failure' and it works still?!

[Despicable]

I know there are about a hundred threads related to the infamous 'spoiler control failure' appearing at 75 ish mph and beeping above and below this speed...very annoying!

 

Mine appears to be a little different than normal though, I took it right back to the motor, confirmed that its getting power properly and the dash spoiler switch works fine too  (orange LED works and it makes the spoiler go up and down no problem manually) but for some reason it still throws an error at 75mph.

 

It seems like the automatic mode is faulty as it will go up as it should - recessed when starting up from cold and goes up at 75mph no problem - then it won't go back down when speeds reduce. To bring it down I have to press and hold the button.

 

Anyone had an issue like this? As I say, in manual mode it will go up and down no problem from button.

 

There is a ducktail spoiler fitted but it doesn't weight much and does not interfere with the fit/boot area.

Is there a spoiler control module that you could have some one probe with a voltmeter to see if its getting the voltage to lower while you are driving ?

That is a very good suggestion, from googling it looks like the module might be under a seat. I'll look into it, thanks.

I had a chevy that had a control module for the radio antenna .....................
