If the lights in the console are functional then it is most likely not fuse related. These consoles are notorious for going bad. You can get a new one at the dealership for $250 (!!!), grab one from a wrecker, or I offer a repair solution with a lifetime guarantee. Check out www.autoclockrepair.com I have removal instructions and info there. Please let me know if I can be of further help, thanks!

Outside temperature display don't work


If the dome lights work and the console display is dead then it is not a fuse issue as power is directed to the entire assembly.
This is a very common problem with many of the mid 2000 Ford truck and SUV overhead consoles. The console is very prone to internal failure. I offer a reasonable repair service with a lifetime guarantee, check it out: www.autoclockrepair.com
There is a bunch of useful info there. Drop me an email if you have questions, thanks!

The compass and outside temp on my 2006 Toyota Tacoma quit working. Is there a fuse for this unit and where would I find it?


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.
If it is not covered by your warranty, check out
www.autoclockrepair.com. We offer a very reasonable repair solution.

Is there a fuse for the overhead compass/temp dispaly for a 2006 Toyota Tacoma and where is it located?


The 10 amp IGI #2 fuse controls several other components including the dome light, cruise control, and brake lights. If these are working but the compass is dim, intermittent, or dead then the control module has gone bad. You can get a replacement from toyota but I believe it costs $500+.
