Hi pixiesjag,

Not to be a nag, but the use of periods, capitalization and line breaks are highly valued on this forum in order to promote ease of reading and clarity of message.

You should be able to test the voltages at the antenna motor harness connector to confirm that voltage is present during the 20 seconds or so after the radio is turned on or off. The polarity of the voltage changes depending on the direction of motor rotation, and this change in polarity is accomplished via two relays mounted on or near the antenna motor. One is the UP relay and the other is the DOWN relay. If you have no power at the connector, check Fuse 6 in the Right Fuse Box, which may have blown due to your seized motor.

At the link below you can download the wiring diagrams. The antenna motor schematic is on pdf page 61, and the relevant fuse is shown on pdf page 7.
