GS430 Power Supply & cigarette lighter not working, fuse already replaced
Hello,
I have an 06' GS430 Lexus and my power supply outlet & cigarette lighter outlet will not work. I replaced both fuses and as soon as i turn on my ignition both of the fuses blow out again. Can anyone help with this issue? Thanks!!

Which 2 fuses? I am away from the manuals, so cannot see the diagram until next week.
There is apparently a short to ground somewhere in the wiring after the fuses. If you can get a high resolution digital ohmmeter, connect one end to chassis ground, and measure (with the fuses removed), the 12V wire. It should be a open circuit. If it reads a short, then compare the readings as measured at the output of the fuse to the reading at the lighter jack. One might read lower than the other, which will imply something about where the short exists.

Sounds like you have a short somewhere, I would look inside the cig lighter socket to see if theres any metals or something allowing it to ground.
If nothing is blocking the lighter then I would pop open the console and unplug the lighter, and see if it blows the fuse. If it doesnt then your cig lighter might be internally damaged.
Also have you had any aftermarket wiring done, because a lot of people like to use the power supply from cigarette lighter. They could be causing the damage as well.
