Spoiler fault - not going down

[_Dan_]

Hi All,

I have a fault with the rear spoiler in that it raises at 75mph but then doesn't retract - at which point the light in the dash comes on.

Holding the manual switch in the footwell in the 'down' position causes it to drop about 1/2" but no more, the spoiler will not do anything then until I cycle the ignition so I'm assuming the control module has gone into fault/lockout at that point.

Fuse & relays all seem to be OK, I've had the spoiler unit out of the car and it motors up & down fine with power jumped directly onto the motor, both limit switches appear to be OK (one is closed at top of travel, the other is closed at bottom of travel)

I've currently got the fuse out to stop it getting stuck in the 'up' position, but the warning light comes on at 75mph when it tries to raise the spoiler and can't.

My next step is to investigate the control module itself - does anyone know where it is located on a year 2000 986?, or have any wiring diagrams for it?

Any other ideas?

Many thanks,

Dan
