Here's all my info on CC stuff. Hope something here will help you or anybody else having issues.
1) Decent
writeup on troubleshooting
Here's
another one on just looking at the Amp...not much good info but pretty pictures
These last 3 are w/o a doubt the most useful. Spend most of your time looking at these. There are several OTHER articles regarding troubleshooting that I did NOT list but can be found on the site...just look around.
LINK PAGE for several excellent articles....take your pick.
PAGE to pick your year actuator for troubleshooting.
And finally, a great guide in how to
TEST your actuator...based on a chosen year for example.
If you can't find the problem or at least get close after looking through those last 3....then I don't know what to tell you.
