Truck is 4 months old....very frustrating. I know toyota won't fix it because I added stereo pieces to the truck.
I think it occurs by grounding a wire inside the string with power in the system.And how does this happen? Is it by a load on the wire somehow? Just confused how this can even happen
Did you have to disconnect the stereo or anything and fix what caused it to begin with or did you just replace the MOSFET? Is it in the same place as the Celica?This can be fixed correctly for about a $1.20 part. See attached links, I ordered the part and fixed it myself in less than a half hour.

Awesome! Thanks. I ordered a couple last nightI was installing new switches in the panel next to the gear shift. I wanted the LED's in the switch to dim with the rest of my dash. I accidentally touched two of the wires and voila' no more dash lights. The truck was under warranty so I was going to let TOYOTA do a hunt for the "defective" part and replace. Well the dealership closet to my house in New Orleans kept the truck for four days and couldn't find the issue. SO I downloaded all of the TIS manual and went to studying. When I finally read all the schematics and all the posts I could find, the link I posted above led me to the correct diagnosis and part buy. I bought five pieces of the MOFSET, in case I blew another one, and took it apart one afternoon. You have to remove the combination meter (gauge cluster) and take it apart. Once you get to the board inside, there is only one MOFSET on the board. Unsolder it and replace. Put everything back in, and back to working. All in all 30-35 mins total. The switches I put in are from On Board Air. I modified them so the LED on top is lit when in "ON" position, and the words light up when the dash lights come on, and dim with the dimmer switch. The second picture has an arrow pointing to the location.
Hey.. got the same problem. Glad you found a solution!! Where did you order the MOSFET and do you have a part #? Does it need to be resoldered?Believe me I know how you feel. I wanted the dimmer switch to function, because it was there! I will always tackle something like this myself, but only after coming to these message boards and reading up on things. The wealth of information from people is truly astounding. The gauge cluster comes out pretty easy, just pull the panel over it off slowly and not force anything. The only issue I have ever encountered is trying to get it back on with the a/c vents attached. Once you do get it out, go inside and take your time taking it apart. It was the first time I ever pulled gauge needles off, but again, after reading up on this site, I was confident in doing it. It is a great source of pride to be able to tell the dealership technicians (3 in fact) that each spent a day on trying to find the problem, that it was a part less than $2 to fix. And it was done in less than an hour!
Thank you! You sir are awesome for figuring this out! My cabin has been dark for almost 2 years!
