Default Grounds

Where are the grounds on an '86 coupe? I've found the one on the left door frame, but I read in one of the 'Vette magazines that there may be nine or more additional grounds.

Default Grounds?

My car has problems with the Heat/AC blower and "Digititis" of the dash. I would really like to find all the electrical ground points and be sure each thing that is attached to them is well grounded. All the problems I have are intermittent. This suggests that poor electrical connections may be responsible.

Any help will be greatly appreciated. I have owned this vehicle for seven years. It was sold new in a small town about 90 miles from here. There have been one or two other owners. I don't know who they were or if they had any problems with the car. Current odometer reading is 80K and this squares with the clean Carfax report (69K) when I bought the car.
