Hi, yesterday I was so stupid to burn my footwell lights possibly trying to upgrade with a brighter LED bulb on my GS450H - 2014.

Now I have done some research and found out that there is no fuses, only 1 for the DOME, and its fine. So it must be the integration relay - which GS450H have 2.

So my question; does anyone know if its the integration relay 8264130330 or the no 2 integration relay 8264130340 that controls the footwell lights ? They sit just next to eachother in the front with the main fuses.

Yes, I am a fool... now I have to make things good again, so hope someone knows. PS: Should be same om GS350 and GS250.

 

is ur dome light working? rear footwell working? both front footwell light not working?

 

Yes. Also light in start button, but lights in the passengerdoors rear is also out.

 

try checking these fuse: 7.5A LH J/B-B, 10A LH-IG, 10A MPX-B, 7.5A ACC, 10A LH-IG2, 7.5A AM2 . the fuse should be in the passenger side and the front driver side first fuse box.

 

Thanks a lot for the suggestion, I did check all fuses allready...

 

PS Both front and rear footwells are not working...

 

if u really checked all the fuse then mybe its ur integration relay then. cause theres a fuse that supply power to it. I don't think a bulb will burn out the integration relay. when I changed my trunk bulb to led I took the oem bulb out and burned the some of the fuse and made all my interior light don't work. I thought I checked all the fuse too but when I look at TIS it shows the passenger side have a fuse box too so I checked and some of the fuse were blown and I put in the new ones and everything works again. you should double check all the fuse since we got like 4 fuse box in our car and check with mybe a fuse tester so it light up when u test it instead of picking out and the fuse and check

 

OK, but I have been in both passenger and drivers side under the dash, checked them all. In the hood as well. I have read some threads that other burned their LS models integration relay as well, so I assume thats where I send.... damn ... anyway in GS 2013 models there is 2 integrationboxes, and I dont know which one controls the footwell light.... hoped someone knew that

 

the one on the passenger side

 

they are placed in the hood both of them...

 

 

It might be, if you know what part it can be then please let me know, I would be very happy to solve it I am not master to read these circuits and my local dealer dont know where to start.

This is the link for the other Lexus that got repair of the integration module:

are u putting it in urself?

 

Looking at this screenshot, its actually exactly the same lights not working in my car as listed there on this circuit.

Front footwell
Rear footwell
rear ambient lights in door
and rear door handle illumination

So where does it get the power? Can you see that and partnumber?

 

PS: No, Lexus will do it, but they dont know where to start, will take many Lexus manhours they say to find out ... crazy.

Tester says nothing by the way (already tried)... but its the above circuit for sure not getting power ...
