Thundercow Posted October 28, 2009 Share Posted October 28, 2009 I changed out my 04 battery. I have the usual window problem now but some other problems as well. Please save me a trip to the dealer! The one I can't fix is the cd player doesn't play, cannot be selected, and the power button on the radio cannot turn on the radio. I have an ipod adapter installed. This happened once before to me, and someone told me a trick that I cannot now remember. Quote Link to comment Share on other sites More sharing options...

joe913 Posted October 28, 2009 Share Posted October 28, 2009 I have a document that helps to troubleshoot the 2003 model electrical system, including audio. If you think it will help, give me your email address and I will forward it to you. The file is larger than the 2MB maximum for this site. Good luck Quote Link to comment Share on other sites More sharing options...
Thundercow Posted October 28, 2009 Author Share Posted October 28, 2009 Actually, it was a reset sequence of some kind like disconnect battery for 20 minutes or something like that. But of course if I could remember it, I'd just do it. Quote Link to comment Share on other sites More sharing options...
ThisIsBob Posted October 30, 2009 Share Posted October 30, 2009 I'm getting ready to change the battery in my 2002 RX300. Has anyone ever used one of these to save the settings: http://storeworth.com/product/9-Volt-Batte...mory-Saver.html? Do they really work?

carguy07 Posted October 31, 2009 Share Posted October 31, 2009 I'm getting ready to change the battery in my 2002 RX300. Has anyone ever used one of these to save the settings: http://storeworth.com/product/9-Volt-Batte...mory-Saver.html? Do they really work? They work great on other cars but the RX kills the cigarette lighter when the ignition is turned off. Is there a plug in the back that is always hot? That might work. Whatever you do, do not kill the battery with the ignition switch on. Bad things can happen. Quote Link to comment Share on other sites More sharing options...
Thundercow Posted November 10, 2009 Author Share Posted November 10, 2009 Just to complete the thread...what worked for me was disconnecting the negative battery terminal for 5 seconds...everything was fine after that... Quote Link to comment Share on other sites More sharing options...
