Last summer the toothed plastic leader in my NB antenna mast broke. When I turned the radio on or off, the motor in the trunk would whir for 10-15 seconds but the antenna didn't move. So I unplugged the three-wire connector from the motor assembly and left the antenna in the "up" position over the winter.
This week I got a replacement mast, and followed the generally accepted replacement procedure: take motor assembly out of trunk, disassemble it, remove old toothed plastic leader, re-install motor assembly in trunk. But, when I got to the point where you try to feed in the new mast/leader I get nothing. There's just dead silence from the motor assembly when I turn the radio on and off -- it doesn't even try to move.
The owner's manual shows two fuses labelled "auto antenna" (one under the hood, one next to the driver's left knee). Both are OK.
I took the motor assembly apart again and I can spin the motor shaft by hand and it spins freely and feels like a high-speed DC motor is supposed to feel.
Since I had it appart anyway, I reassembled it with the antenna mast installed in the down position (seems a bit simpler than trying to feed the leader in while the motor is spinning).
But, the motor still doesn't spin.
Any ideas what to do next?
