Spoiler won't auto retract

[amagalla]

Hello all,

My spoiler won't auto retract at 45 mph anymore. It goes up at 75, and I can put it up and down with the switch, but it won't auto-retract. Another strange thing is when I manually put it down, when it gets to the bottom, there is a "tap, tap, tap" noise that wasn't there before.

Any ideas?
