Toyota tacoma temp & compass not working

SOURCE: 2005 Toyota Tacoma 4x4

I found the solution to this on one of the Toyota Tacoma forums, there is a service bulletin out for this particular problem, a replacement circuit board to do a factory repair is 800 to 1000 dollars depending on which Toyota dealer you want to throw your money at.
The way you get the overhead console apart is to open up the sunglass holder and remove the lone screw in the middle. Some say it is a Torx head screw, mine was a phillips which I promplty dropped into the far reaches of the passenger seat and had to retrieve ith with a magnet.
Once thats done, grab the front of the console between it and the headliner. I tried a nice steady pull but I think it would be better to use a quick **** to dislodge the clips. It is a little scary because I'm sure the console is high-dollar too. Pull straight down to keep from breaking off the plastic posts on the console. The bad part for me was that when it all came apart, the metal clips came off and one is now lost in my headliner somewhere. I went to the local Toyota parts department, and yea they can get me a replacement, I have to order a minimum of ten at around $8.00, the other thing is, Helena MT.is a geographical oddity, two weeks away from anywhere. Whatever happened to customer service? I have a theory.
So, once you get the console down, disconnect the two connectors, one for the temp and one for the map lights. The console comes down, you can slide the connector off the console for the map light, and using a T-10 screwdriver, remove the three screws holding the circuit board to the console. Remove the lens from the circuit board and you should be able to see the 510 resistors. The one that came loose on mine was pretty easily seen. To verify this is the problem with the nonfunctioning indicator, press on the resistor with the unit plugged back in the truck, it should light up. Keep in mind, while you are admiring your troubleshooting expertise while holding the resistor down, those bad boys heat up pretty quickly.
I was able to solder mine back on very carefully using my weller gas powered soldering iron and some .032 diameter solder, use a clean, newly-tinned tip and it should be fine. Be careful not to heat the board too much.
Installation is the reverse of removal, unless you lose a clip, good luck finding those.

Are your cruise control, dome, and tail lights also out? If so then it is a fuse. If not then the control unit has gone bad internally. You may be able to get it fixed under your warranty.
