Can you clarify? Are you saying that the illumination lights for at night are not coming on or are the warning lights not coming on? If it is the illumination lights are you certain the rheostat dimmer is not turned down and are the running lights working?
Do you have any test equipment like a 12 volt test light? The 10 amp tail light fuse feeds the dash lights. It is in the fuse box under the hood. If the tail lights are working then the fuse is good because it uses the same fuse. Did you check the tai lights?
Any parts store sells these fuses. Make sure you have the right fuse location. If you look in the lid of the fuse box cover it will give the identification and location of each fuse. If you are still uncertain about the fuse let me know and I will see if I can find a picture or diagram. I find it hard to believe that the fuse is just missing. But the tail lamp fuse is the common problem for the taillights and the dash lights. Let me know what happens.
No this is a tail light relay the fuse is located in the diagram below in the box under the hood. Click the link to enlarge. Do you know what fuses look like? If you go to an Auto Zone they are usually good about helping people put a fuse in or at least checking it.
Where did your taillight really go? If you have a defog relay or a fog relay grabbed it firmly and pull it out. Then stick it into the slot for the taillight relay and see if your taillights function. They should be the same relay. The relays are in tight. Let me know how it goes. I will be taking a break for a few minutes and I will check back in a while.
I would take the relay to the parts store to have them match one up. There will be a Toyota part number on the side of the relay. They should be able to cross-reference that number. If they cannot I would go without fog lights for a day and pick up the right part at the Toyota dealer. The actual relay is called taillight relay. The fuse is a 10 amp taillight fuse. All fuses for this vehicle are the same type just different ratings. If you want to order a taillight relay online go to www.metrotoyotapartsnow.com . Let them know I sent you. They have good prices and they ship in the US. This way you will get a factory taillight relay all you have to do is plug it in and go. At least now when you go quietly into the night you will see your way. Just kidding I am glad you found the problem and didn't cost you $100. That is unless you're feeling generous with a just answer bonus. Have a great evening. If you need anything in the future just ask for me.
