This morning started as usually, noticed that gear selector (PRNDL) doesn't light up, winter mode button doesn't light up, sport mode button - the same. Power steering feels heavy, TC light came on, Check Engine light on. Car drives reverse fine, forward - feels like in winter mode, 3rd gear... Reads U2106 code. Looks like the whole transmission and related electronics doesn't get power... Is there a fuse or smth? TCM looks in place :)

Any clues?

Update:

Traced the problem to fuse 3 10A (FLASHER).

After changed the fuse - everything is OK, press the brake - OK, move selector to R or further - no lights, blown fuse.

Confused...

Looks like solved the problem... At least found what could cause it - broken wire under the trunk lid that goes to reverse lights.
