owners/service manuals
C5 CHICK
I did not mean to suggest the owners manual would be of any help. GM produces a service manual for use by the service technicians at the dealerships. It details how to do repairs, services, etc for the car. You can buy the three volume set from GM, probably Ecklers, MidAmerica, and other sources. The retail cost for the service manuals is on the order of $125.00, I think. The advantage to using them is that they show where all the screws are, tell what order to remove things, etc. This may not be helpful for you, but they did help me. I replaced a headlight motor using them, for example. I should have replaced a burned-out running light at the same time, as it was really easy to get to with the headlight assembly out. It is still burned out, but I think I will get at it from below, by removing a close-out panel etc.
Good Luck
