My trunk light on a Lexus ES300 has blown. I went to a auto store and they need the amp size. I took in the old fuse and they sold me a 3 amp and it blows them.

What size amp do I need? I can't find it in the owners manual. It is located on the top on the trunk (not the lid and about 6 inches from the lid edge and in the center

 

You may want to include the year of your ES next time.

No circuit in the car runs on a 3 amp fuse. The lowest I believe is 5 amp.

If I'm remembering correctly, thats the dome fuse? If so its a 7.5 amp fuse.

I can look it up later to be sure but i'm pretty sure its on that circuit. You can check which fuse you pulled on the back of the coin drawer can't you? I think it also says that size there too but I could be remembering wrong.

 

it is 1999. The fuse is a glass type about 1 inch long and in the trunk. I will try a 7.5 amp

 

Wait, are you talking about the "fuse" behind the trunk light cover? That's not a fuse but a lamp.

 

I misunderstood you. Lexus2000 is correct. That's the light bulb.

 

It has 3W on the "fuse" and looks like a fuse. It could be a lamp since the cover is missing
Lexus 1999 ES300

 

3W is 3 watts, fuse have a number on them only. The only fuse compartments on a 1999 es300 are the driver side fuse compartment and the engine fuse compartment.
