I was hoping someone could help me. 1990 C4 where the warning light comes on at 50 mph the spoiler light also comes on and stays on until the reset is pushed for warning light. The problem is that the rear spoiler stays up and will not go down even when tried with manual switch on console to lower. Any suggestions? I was hoping to eliminate the "Dealer".......

 

I'm having a similar problem in that the spoiler on my '91 C2 stays up all the time. I'm hoping it's not motor failure as the motor is pretty pricey. Have you had any luck solving your problem?
