Thanks for the help guys, it was the power antenna. Once I disconnected it the amp draw went away. Once again thanks.....

Get one from a 98 or 99 Bonneville from the wrecker. Drill out the rivets, clean out the gunk, re-grease it, and put it back together with machine screws and nuts. It'* a $20 fix for the lifetime of the car.

Huh? The power antenna on my '99 didn't last more than 45K. That plastic, snaky bit fatigues and breaks off. I wish I could have rebuilt it, as the old antenna had the black tip ball... the junk yard replacement is chrome.

I didn't see a way to swap the actual antenna... to get it off the broken snaky piece.

Both of my cars are running 99 antennas now. Stockers lasted about 80k on one, 110k on the other.

The idea is to get the newest one you can, lubricate it well, and keep using it. The best way to prevent stressing the plastic piece is to keep the mast sections lightly lubricated with a silcon based lube so that it can't freeze. If you extend or retract your antenna with ice on it, that plastic will break eventually.

On my SSE the antenna wouldn't shut off so I just unplugged it in the up position. Works great now (my cars never see an automatic car wash). I like the idea of finding a 98 or 9 antenna and rebuilding it. Maybe I'll look next time I'm at the yard.
Wonder if I should just try re-lubing the one in the car?
