Hey all,(
I don't know if anyone is electric-savvy here but I just wanted to see if anyone could possibly know the issue. I was taking out the interior light (the middle light in the cabin) and i touched my metal pry bar against a bare metal surface and it created a spark, and after that, my trip computer got reset, my sunroof won't close, and my daytime and side marker lights don't work anymore. I tried different bulbs but still the same. I don't know what to do. I did check both fuseboxes and no fuses were blown, which was my fear.

 

Plastic is your friend.

What year LS400?

Anything else not working?

 

I have a 1990 LS400. USDM. And the courtesy lights, seatbelt position button, and power locks. My windows still roll up and down though.

 

This suggests a fuse or perhaps a fusible link.

Did you actually extract fuse for the dedicated circuits, or eyeball them from the top while still plugged in?

In any event, it wouldn't be wrong to clean the fuse box sockets and replace all of the 30 year old fuses and fusible links...

I did extract all the regular fuses and inspected them, none were blown. I even replaced the ones related to the issue I'm having with new ones to no avail. The fusible links are all transparent so I could see that nothing was melted. The three circuit breakers I tried pushing fairly hard and no click. I tried different objects too. I did look in the driver kick panel as well as the engine compartment. However, I did not completely remove the fusible links or the circuit breakers. Should I do this? and what should I look for.

 

On second thought, it was a fuse. I was just being a dumbass and didn't see that it was broken even though I looked 4 times.

 

1990-1994 LS400 use the larger bladed base fuses?

The fuse links were provided to present oxidation/corrosion of fuse blade/plug contact area after 20 years.

Perhaps you would be willing to post several high resolution images of your 30 year old fuses.

Thanks
