Lexus RX 2004-09 :: Nav Screen Not Working After Fuse Fixed?
Nov 11, 2014
04 RX 330. About a week ago, the car died on my wife. The instrument panel was working but nothing else, no radio, windows, steering column, etc. We replaced the battery and had the same problem with the new battery.
Working through all the fuses & relays, I discover the main fuse, 140amp fuse link, had gone bad. The fuse is bolted on the sides with an 8mm and a 10mm bolt. After taking the fuse box apart, to be able to get to the bolts and remove the fuse, I replaced the fuse, which happens to be a factory only fuse, couldn't find it at any local auto parts stores or amazon, the car started. I have windows, steering column, radio, chair, etc. The only thing not working now is the navigation screen, which also controls the AC/Heat, and the back up camera.
I've gone through the manual and have checked every fuse that has any reference to nav screen.

Alright, I can use all of the manual functions fine which includes climate, radio, audio etc... but the touchscreen system is not working. It seems to somehow be disabled or malfunctioning.
What can I do to fix the problem without having to buy a whole new system!! (costs too much!!).
I am thinking that a fuse may be bad but which fuses go to the navigation touch screen.

So yesterday I had Error 3 code display on my cd player and after messing around with the device i was able to get it to eject all the cds. Thinking all was well, i tried to load one cd and it won't even respond to me pushing on the button. There is no noise or error code coming from the unit. Whats going on here?

I got an 07 LS460 without navi but it still comes with a screen. Last week, the display started to work only intermittently and got pretty pissed. Last night was driving without the screen, but when a passenger stepped in, the jolt kinda made it work all over again. However, this morning it didn't work again.
I brought it to the stealership today and they claimed that the fuses are all working and its the screen that is spoiled and has offered to replace it for about 12kUSD. What do you recommend me doing. But first I am gonna try to remove the battery for 20mins tonight to see if it gets better.

For the past few days, every time i turn the car ON (with the headlights ON), the nav screen, clock and surrounding buttons illuminate as they should, but after ~3 seconds, the illumination for the surrounding buttons and clock shut off.
Also, the touch-screen functioning and surrounding buttons do not work at any time. The nav screen remains illuminated, however the touch-screen buttons and surrounding buttons do not work. If i turn the car off and restart, same thing; all lights illuminate for about 3 seconds then stop.
During the day with no lights on, the clock will illuminate for ~3 seconds, then shut off just like above. None of the surrounding buttons (climate, map, infom audio, display, etc) work at all.
What would cause this unusual condition? I feel like if a fuse were blown, it wouldn't work, period. But, the lights illuminate for a few seconds before shutting off.
The emergency flasher button works and illuminates always, and the passenger airbag lights do, likewise. I pulled the nav unit from the car and checked all cables, and they all appear in place.
I can communicate with the car via the voice commands, but that's it.
what might be causing these strange symptoms?

When backing out of same parking spot, I always hear a clunk, clunk, clunk, noise in the front while turning the steering while back in the fixed position. I have heard this noise in the past but did not think any thing of it.
It's hard reproduce this noise, it seems to only be happening when backing out and turning the steering wheel. Car only has a little over one thousand miles.

The info screen on my 2005 Prius shows up black. When I push one of the buttons, it gradually goes to its normal brightness, stays that way for about 10 seconds, then goes black again. The buttons all work while its lighted.

Right Front Seat Stopped Working. It was about 2 months after I got the car or 2 weeks after I had it hardwired for a Police Radar power source. I'm pretty sure it was working after the custom police radar power source. I haven't even used the power source since I'm still waiting for the radar to come. So, I don't think it was that or maybe yes.
I went to my dealer and it was there for about 2 days trying to figure out what went wrong. It turns out the 30 amp fuse blew up or died.

We bought this car a month ago, 2007 US touring model. It had a 15A fuse in the Gauge position (spec calls for 10A there) when we bought it. As of last week it is blowing a lot.
What we've noticed:
- First time it happened I noticed my signals weren't working. After 5 minutes of driving I pulled over and turned the car off and on. At that point the Combination Meter went blank. After getting home I found the fuse blown. Replaced it with a 10A fuse, and that blew right away when starting the car. Replaced it with a 15A fuse and it worked for a few trips.
- While I was away for a week, my wife replaced the fuse 3 times while it blew away from home. (she estimates every third trip) She has found it seems to happen when putting the car in reverse.
- Today the car is working fine, and I can't replicate the problem.

My rear window defogger has stopped working. The owners manual, page 316, has the 3 fuse box locations and it says there is a 40 amp fuse in location #2 in fuse box under dash (says there is a 30 amp in location #1 for power windows). When I popped the cover off the fuse box and looked - there are NO fuses greater that 25 amps anywhere. Windows work fine. in addition - none of the actual fuse numbers line up with what the manual says or with what the inside of the fuse box cover says.

I'm new owner of 2003 GX and just tried to play a DVD in the rear seats for the first time. DVD loader is below glove compartment, passenger side, and monitors are in the headrests. Was able to get power on via the remote, and load the DVD, but could not get the rear screens to come on or the DVD to play. Perhaps the little white rear seat remotes weren't working? Is there another way to get it all going once the DVD is inserted? Couldn't find anything in our owners manual that explained.

Had to get a replacement battery for my 04 GX470. The garage replaced mine with the same model. Turns out the model changed, poles were reversed and I hooked it up backwards. Realized I did something stupid so I took it back and got another replacement. It cranks over now but I have no display screen, radio, climate control, power windows, power seats, and I'm guessing more. I am guessing a few in my engine compartment as well as the drivers side kick. Thing is, not sure how to tell if the engine compartment fuses are blown or not.

In sunlight my Nav screen is unreadably dim. Is this normal? I just got this 2005 GX, my first, this month and have not had the chance to compare it to others.

Display screen blank- radio and AC work but cant control on touch screen (its blacked out), tried a few tricks that others had suggested
like hold info and cycle lights 4x
removed positive battery cable and replaced
held menu for a minute
etc etc
Gave up. Went to dealer expecting a unpleasant $$ (buy a new nav screen) type of surprise. nope! service writer pulled it in to the shop and ....
Disconnected the NEGATIVE battery cable. Fixed it right away and didn't charge me a thing (shouldn't have anyway) He said that sometimes the computer just gets scrambled and shuts itself off as a precaution. So if you nav screen is blacked out and unresponsive give that a try.
