My spoiler has decided that it will not go down as it should. No probs manually and has once or twice worked automatically. I've searched the forum and checked what I can - limit switches- okay all the way back to controller, main controller - nothing obvious in there looks bad, joints e.t.c.
Question is, is there anyway of actually testing the controller to see if it is okay?
As mine is a 90 car anybody know what function the additional controller has as the main controller is the same as 91+ cars without this? (parts manual says use new part no. in place of old one) The spoiler still works manually with this removed but have not tried it automatically.
Am I right in saying that the speed signal comes from the rh rear abs sensor and is this used for up and down?

Thanks

On a 90 model, you're not quite right about the speed signal. There is a separate speed sensor on the transmission tunnel and this controls the spoiler. If this fails, then the ABS sensor will be used (although I didn't know which wheel it was) - but then the spoiler doesn't raise until 75mph (or might be 70mph, can't remember). This is only true for 89 / 90 models.

I suspect the easiest way to test your control module would be to try it on another car - is there anyone near you? Where in the UK are you?

Thanks Dave,
The spoiler raises at 50ish so I assume the speed signal is okay?
It looks like the control probably, this was apparently changed by the dealer when I bought the car 4 years ago so unless they put a secondhand one in it looks like I might have been unlucky! The spoiler would not raise then.
It's not that much of a problem so when I get time I'll do some more digging!!
