1997 DeVille - power antenna stuck up, motor trying to retract
Read some posts on this, for other GM cars. Pretty common. Its stuck up. Motor whirring with the radio on. Gentle pressure not retracting any of thre telescopic sections, so stuck up. When first given this car my brain never even thought of an auto antenna, let alone one that came up/down with radio on. So, yep, I took it it through the carwash and since I had the radio on it was up.
Now it is slightly bent at base. Not a lot, but probably enough resistance to prevent motor from pulling retractor cable down. AntrennasRUS has a repalcement mast and cable kit.
Main question: can I just disconnect the wiring clip from it until I get new part (and when I work on it)? I thought I read somewhere that you cant just unplug it because the computers dont like that for some reason. That there was a special way to do it.

You can disconnect it.

Antenna: Description and Operation
When the radio is turned "ON," voltage is applied to the antenna relay coil. The antenna relay contacts close, and battery voltage is supplied to the antenna motor. The other motor terminal is grounded through the antenna motor "UP" switch, and the antenna relay contacts. The motor drives the antenna up. At the end of its travel, the "Up" switch opens and the motor stops.When the radio or ignition switch is turned "OFF," battery voltage is removed from the antenna relay coil. The contacts open, applying battery voltage to the WHT wire.
The DK ORN wire is now grounded. Since the "DN" switch at the antenna is now mailing contact with the WHT wire, the voltage to the motor has reversed polarity. It runs in the opposite direction and drives the antenna down. At the end of its travel, the "DN" switch opens the circuit.
The antenna is connected to the radio by RG-62 type coaxial cable.
