Antenna fuse location
Does anyone know the location of the fuse for the power antenna on a 85 coupe? I looked at the fuse block on the passenger side door but I do not see it listed there.
My antenna does not go up or down. I hear the relay click when I turn the radio on and off so I thought it was the antenna motor since the mast was broken and you could raise or lower the mast just by puling in. I pulled the antenna out and aplied 12 volts to the motor and it turns. I don't know if it is the fuse or the relay that doesn't work but I figured the fuse would be easier to check then the relay.

The antenna motor gets its 12 volts from the CTSY/CLK fuse which is hot all of the time.
If your interior courtesy lights work, the fuse is good.
The Antenna relay is located towards the driver side under the black plastic trim piece that covers the rear hatch lock/release latch.
The relay has the following wires.
Pink is 12 volts and goes to the primary of the relay. When you turn the radio on the relay should energize.
Orange wire is 12 volts from the CTSY/CLK fuse for the secondary of the relay and applied to the Antenna motor.
Black wire is ground for both the primary coil of the relay and secondary contacts of the relay.
The White wire, Dark Green wire and Gray wire go to the Antenna.
The Antenna has two internal switches inside of it which open or close when the mast is extended or down
The position of the switches and the voltage polarity applied to the Antenna motor via the relay contacts determines what direction the motor turns. (Mast will go up or down).
(Power Antenna will not Extend or Retract)
Verify you have 12 volts between the orange wire and black wire.
Disconnect the 2 connectors from the relay.
Ground the gray wire.
With a fused jumper wire, short the Orange wire to the Dark Green wire. The mast should extend. If not the Antenna assembly needs to be replaced.
With a fused jumper wire, short the Orange wire to the White wire. The mast should retract. If not the Antenna assembly needs to be replaced.
If the results are correct, the relay is bad.
