Default TCM failure, 4x4 indicators out

One day a week ago just jumped in started my 2006 H3 and I have the TCM failed warning and none of the indicator lights on the 4x4 are working. Is there a fuse to these? If so which fuse is it? Otherwise is there another fix to this?

ya I'm sure there's a fuse, but I don't know where. I've heard about bad connections at the transfer case, but haven't experienced any problem like this personally. Try searching this and other forums because I have seen threads before about TCM probs

The reason I said maybe fuse is because the day before I had problems with my blower motor and was messing with the fuses and then all of a sudden the next time I drive it boom, the "Traction Control Failure" code comes up.

Check TCVM fuse 12. I intermittently get Stability System Failure... every time fuse 12 (30amp) is blown.
