00 maxima power antenna problem

I need help, i have a maxima with a power antenna sitting in my bay tonight because i cannot figure out why the antenna will not retract up with the radio tuner on.  i checked the voltage with a DMM on the remote line and power antenna line from the deck (pio deh3700) and had around 12v.  just to take it one step further i used a in line fuse holder with a 5amp fuse to jump swithced 12v to the power antenna, which was BLACK/ red in my notes. what i noticed was a relay clicking and the stereo only played audio while the 12v was connected to the BLACK/ red wire. when i took the 12v off the audio did not paly anymore but the stereo was still on.  the customer was convinced that the power antenna worked before he brought it to us.  I also tryed to reconnect the factory radio to see if it helped and I checked all fuses in both inside fusebox in the car and the fusebox under the hood. I think its the antenna motor that has went bad.  Does anyone have any ideas as to what could be the problem? 

the wiring I have says GREEN / WHITE for the power antenna. You may have your jumper connected to the factory amp turn-on.Life moves pretty fast; if you don't stop and look around once in a while; you could miss it.
