95_LS400 Posted December 12, 2008 Share Posted December 12, 2008 I did a search and I found instructions on how to replace the antenna mast on a 1990-94 LS400. It was helpful in helping me get the retaining nut off, but unfortunately that was about it. I tried turning the radio on and pushing the "AM" and "TAPE" and "AM" and "CD" buttons at the same time while the key is turned to the ACC position, but it doesn't work. What needs to be done on the 1995 model to get the mast out? Thanks -Joe Quote Link to comment Share on other sites More sharing options...
AzHotLS Posted December 12, 2008 Share Posted December 12, 2008 It should be the same. Do you hear the motor running when the antenna should be going up or down? If no, first check the 10amp fuse under the hood. Quote Link to comment Share on other sites More sharing options...
95_LS400 Posted December 13, 2008 Author Share Posted December 13, 2008 The motor runs, but it doesn't run for enough time to fully extend the mast. Quote Link to comment Share on other sites More sharing options...
AzHotLS Posted December 13, 2008 Share Posted December 13, 2008 Oh, I just replace my power antenna assembly with one I bought of of eBay that came off of a 96. It doesn't seem to extend all the way up either. It could be that the cable is broken inside. I should have taken the time to take a look at it before I installed it. If it is broken, out it will have to come to open it up and see. That's probably what you're going to have to do as well. Quote Link to comment Share on other sites More sharing options...

If it were broken, the mast would still come out, but the broken portion of cable would remain inside. The motor still has a firm grip on the cable, I can feel it when I try to remove the mast.

AzHotLS Posted December 13, 2008 Share Posted December 13, 2008 I found this thread: http://us.lexusownersclub.com/forums/index...?showtopic=4209 Not sure why it's not working for you. You're not pressing all 4 buttons are you? Just AM and CD? Just did it on mine. Got it out and back in. I guess it is extending all the way up, just not as high as I thought it would compared to the 90 I had. Now I know my cable is fine and all the teeth are good.

95_LS400 Posted December 13, 2008 Author Share Posted December 13, 2008 I'll try pressing the AM and CD buttons again in the daylight. I'll let you know how it goes. Quote Link to comment Share on other sites More sharing options...
