How To Replace a Defective Telescopic Antenna
Now this is a simple mod and the OEM assembly with motor is $130+. You'll know you have the problem because the antenna won't fully retract
Parts:
Adjustable wrench
GM OEM Power Antenna Replacement ($13 E Bay).
Make sure the antenna is fully retracted and that the radio is off
Remove the antenna mounting nut located on the base of the mast on the outside of the car. If the mast is bent it may be necessary to cut off the old mast). If you can't all of the plastic cable out as one piece, (sometimes the plastic gets really hard and breaks into pieces then falls down into the motor), you can just pull the motor after you have pulled the mast out and get all of the pieces out. To do that you'll need to take out the outer right turn signal housing.
Turn on the radio and pull out the old mast and serrated cable completely out of the antenna motor. (Note which way the serrations on the cable are facing)
Feed the serrated cable of the new mast into the antenna hole and stop when resistance is felt. (about 12”). Make sure the cable is fed in with the teeth the same way the old cable came out.
Turn the radio off to lower the antenna until the serrated cable catches.. You may have to cycle the antenna a few times until the cable catches the gear mechanism and retracts into the antenna motor.
Replace and tighten the antenna nut into the mast base.
Turn on and make sure that the mast fully extends without binding. Clean the surface of the antenna to remove any adhesive etc.
10 minute job.
