Corvette Clinic’s Chris Petris gave us a tip on keeping the door handle working like new. While holding the handle in the open position, spray penetrating oil onto the springs. Use plenty, as it will also seep through the drain holes on the bottom of the door-handle housing. This will help oil the linkage inside the door. The mechanism must be lubricated frequently because the handle is located on the top of the door, where water can easily wash off the oil.
