2000 Corvette: Service Bulletin: Power Antenna Not Working Properly or is Completely Inoperative

Number: 00-08-44-006A
Subject: Power Antenna Not Working Properly or is Completely Inoperative (Replace Antenna O-Ring Assembly/Cap Nut & Clean Mast)
Model Year: 2000 Chevrolet Corvette, 2000 Pontiac Firebird, 2000 Chevrolet and GMC G-Van

This bulletin is being revised to change the labor time. Please discard Corporate Bulletin Number 00-08-44-006 (Section 8 -- Body & Accessories).


Some customers may comment on the power antenna doing the following:

  • Will not go up all the way
  • Will not go down all the way
  • Will not move at all


The O-ring/cap nut material may not be compatible with the lubricant used on the antenna mast. This incompatibility may cause the O-ring/cap nut to enlarge and place a drag on the antenna mast, restricting its movement.


Inspect the antenna mast and housing for damage (bent mast or housing). If damaged, perform the normal non-warranty repair. Otherwise, if no damage is present, perform the following repair:

  1. Turn the radio entertainment system to the OFF position.
  2. Place the ignition key in the OFF position and remove the key from the key switch.


    Do not allow the antenna to be activated while the O-ring assembly/cap nut is removed from the antenna. Allowing the antenna to activate with the O-ring assembly/cap nut removed will allow the antenna mast to come completely out of the assembly.

  3. Using an adjustable wrench, loosen and remove the antenna O-ring assembly/cap nut.
  4. Install the new O-ring assembly/cap nut to the antenna mast, finger tight, then tighten 1/4 additional turn.
  5. Place the ignition key in the key switch and turn to the run position. Turn ON the radio.
  6. With the antenna in the full up position, clean the mast with a clean rag.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
