... another power antenna ??

Greetings gang,

purchased an s4 recently where the PO installed an aftermarket radio, fudged the wiring it seems and the power antenna is frozen in the up position. it worked the moment i turned the ignition over after the auto was delivered and that was it.
checked the relay at the PA unit, looks ok, is there any place else in the fuse box that i can look to sort this out?

thank you!

In the case of my Milano and the 91 164S, the radios worked, so not a fuse problem, but the plastic toothed drive straps inside the tubes broke and left the antennas up.

So, if the radio works, the problem is usually a broken part in the antenna itself, generally the plastic drive strap. Also, the antenna power wire just plugs into the back of the radio (which controls the movement of the antenna), so check that connection.

In the case of my cars, the rebuild kits didn't work, so I just bought new powered antennas from eBay, about $20-25. They have worked fine for years. A little fiddling with the actual mounting may be required, as usually these are universal units, but usually it is no problem, either inside the fender, and the through the fender grommet.

If the radio doesn't work, check the radio fuse (see the owner's manual), and the wiring on the back of the new radio to make sure everything is hooked up and properly connected. Check that the adapter wiring hookup harness, if used, is the proper one for the car and new radio combination.

maybe check the 3 pin connector at the antenna itself (3 wires: a black ground plus a red/black and blue/yellow that go to radio)...undo & clean.
worth a try!
