I fixed one of these recently in a 2003 Outback. The brake light pedal switch feeds the circuit that releases the shift lever lock when it's in Park. (This is why you need to press the brake pedal to shift out of Park.) If the fuse to this circuit is blown, the shift level lock will not release. I traced the issue to the trailer light conversion box (factory/dealer installed, I think). This car has a clear plastic plug that the trailer light conversion box plugs into and the clear plastic plug appears to be a factory-installed part of the wiring harness, accessed on the passenger side of the car, just above the spare tire compartment behind the rear quarter interior panel (you don't need to remove the interior panel to access, just all of the spare tire compartment foam pieces). I've seen these conversion boxes fail before or the wires become shorted somewhere between this internal connection and the trailer pig tail connection end. I unplugged the box from the car's wiring harness at the clear plastic plug mentioned above and the fuse stopped blowing, the brake lights starting working again as well as the turn signal lights and the shift lever unlocked by pressing the brake pedal. This car doesn't tow so it wasn't a problem but you might need to investigate further or replace the conversion box if you need the tow lights connection to operate still.

check all your fuses. If your lucky you might find one the is blown and could be related If not fuse related then you need to remove the platic steering column cover. Under there at the end of the shift lever you will find two small wires that are for the tow haul button. These wires get brittle and break over time from shift level movement it seems. You will have to repair the broken wire and you should be good to go!

You are talking about the trailer option button on the end of the shift select lever ?
I would say a fuse, check there first, and there is also a relay.
As far as I can tell all this switch does is take the tranny out of overdrive, which you can do with shift lever manualy.
If you do not find the problem, you may have to replace the switch.

POWER LIGHT ON THE DASH MEANS YOU INADVERTANLY PUSHED THE POWER SWITCH WITH YOUR THUMB ON THE AUTO. STICK SHIFT LEVER,(ANY WHO..IT JUST MEANS THE ENGINE IS TRANFERRING MORE POWER TO THE TRANSMISSION THAN REGULAR(NO BIGGIE)! YOU CAN TURN IT OF BY PUSHING THAT LITTLE BUTTON ON THE AUTO SHIFT LEVER! HOPE THIS ANSWERS YOU QUESTION!:):):):):)

The lever "pivot" has broken the wire leading up to the switch. Replace switch (I believe you must purchase the entire lever)

check fuses... if ok the wires going to that button like to break ... unscrew handle end and inspect...

tow haul mode will not work on my 2005 chevy silverado, the light will not come on or anything and i tried pushing it while driving and the tranny still shifted the same..

Fuse #23 controls the turn signals, heater blower, reverse lamps, and the shift lever solenoid. There is a hole in the right side of the console where you can poke around with a ball point pen and unlock the shift lever. The fuse is located in a panel behind the glove box. I took my car to a dealer and had them change the fuse, but the ball point pen trick will save you a tow job.
