I'm looking for the clutch switch that disengages the cruise control on my 81 911SC. I have a Bently manual coming in the mail, but I'm trying to rule out the obvious reasons why it doesn't work before the book arrives. Does the servo unit fail often? How about the module in the luggage compartment? I already checked the control stalk and that is functioning properly. Any suggestions for troubleshooting would be appreciated.
