#54 of 82 Front lighter fuse problem
Jul 27, 2010 (1:50 pm)
I have a 2001 Lexus LS 430 -just went on a road trip- I was using a GPs- plugged-into the front lighter -after several hours of driving I noticed the Low battery signal on the GPS come on-clearly the GPS wasn't getting power to it to re-charge. I figured it might be a fuse so I stopped at an auto parts store and replaced with a 15 amp as directed by the manual. After several hours
it blew again, I replaced it again and finished my journey so it is an intermittant short. Do I need a special Lexus fuse or does anybody have any idea how to fix this? I'm killing my back each time I contort my body to replace it! Thanks!

Your message is a little confusing. The GPS first indicated that the battery was low, so you replaced a fuse. Then you said "it blew again". Did the fuse blow out the first time or did you just assume it had?
I had a similar experience with my 2004 LS430, in that the GPS kept saying it was low on power. Turned out the problem was that my car battery was failing. When I replaced that, the GPS problem went away.

Thanks for your reply. The fuse had blown and then blew again after a couple of hours.I replaced the fuse both times and it is currently working and charging-However I was hoping to not do a repeat performance of constantly replacing the fuse. I was on a 7.5 hr road trip today however! May be I should have the battery checked out- altho it is about 1.5 years old- I'm in FL. and the heat kills batteries!
Maybe that is getting ready to go too!

Ok my lexus's radio does not work throughout the day(it does not turn on). At the same time everyday when i get off work at 5pm the radio turns on and works fine. It is the stock radio and the issue is powering on and off. Thank you for any solutions or ideas : )

The GPS charger, cable, or cigarette lighter plug, has an intermittent short.

Depending on how your LS430 was ordered, there may be a second cigar outlet in the back seat, just below the front seat center armrest. If it is on a separate circuit, you could at least keep the GPS operational while you are tracking down the short.

Cigarette lighter outlets are notorious for shorting out because people often put adapters into them which aren't quite the right fit--due to cheapo engineering---and so they tug and twist and this often damaged the wiring or the socket itself.
I'd consider adding an auxiliary 12V outlet from a kit you can buy, and installing it perhaps in the glovebox. I'm sure a radio shop could do this for you for not a lot of $$$.

Yes there is one in the console whichI had forgotten about and one behind the front seats- a lighter- I found a different fuse circuit for the rear one- I'm not sure about the one in the console. Thanks for your feedback!

Thanks very much for the suggestions-I didn't know you could do that... I may check out the other outlets also...since it is intermittant it might cost alot of $$ to repair or replace the socket in the front. I have checked the fuse in the GPS and the cord seems fine so I have a feeling the problem is in the front outlet .
