I was out exercise driving my 87' and turned the radio on. When I got back to the garage I turned off the engine but started hear a buzzing sound coming from under the hood, just under where the automatic antenna recesses behind the right front quarter panel.

I turned the radio off and the antenna came down but the antenna motor never shut off. Fortunately I have the battery rigged up on a kill switch but now, when I start her, the antenna will not come up when I turn on the radio and, if I leave the radio off, the motor continues to run trying to stow the antenna even though it is already stowed.

 

Are any thirdgen owners aware of a quick fix for my ailing antenna?

 

Welcome to TGO. The relay (unhook it and the motor will stop) is under the pass side of the dash. A fix kit is available from GM, I believe. A search will probably find the above part number. FYI, I replaced the whole assembly, which I purchased from GM, a couple of years ago. I don't know if the piece has been discontinued or not. GM 22062580.

Thanks JamesC. Is the relay labeled?

I'm gonna run out to the garage and look for it now.

 

I don't remember the connection being labeled, but it's been about 13 years since I worked on mine...

There's a little plastic line that fits inside the metal antenna shaft that winds up onto a spool inside the motor that is broken. IMO, its probably easier just to replace the whole unit. It's kind've a tight fit up under the fender, but just pop out the inner fender well and you should be able to swap the antenna out.

 

Ordered my antenna unit from GM parts direct a few
months ago that was suppose to be a direct replacement
for our cars. It wasn't Its universal.

Had to fab up a new bracket. Plumbers strap.
Easy to do. 3 wires colorcoded rite, just cut and
splice in. Works great
They also had a repair kit for broken band as yours is.
Relay should be under middle of pass dash bottom lip as both 87s.

Thanks for the info...sounds like a good weekend job.

 

Pulling the wheel and inner fender and even having
to fab up a bracket if needed shouldn't take 3 or 4
hours with (kool Aid) breaks in between
