Replacing power antenna motor?
The long running problem with these is the antenna sheds paint and seizes up. Being in IL, like I am, you are exposed to road salts, which make the problem progress faster.
If you can get the mast all the way up one time, you can try GM's published fix. Take a rag and wet it with 100% mineral spirits and wipe down the mast. Retract it, extend it, and repeat the wipe down until it looks like the mast is operating smoothly.
If you are too far gone for this, you can replace just the mast and save over $100. (If you hear grinding, the motor is working just fine.)
