ok my name is Bryant , I'm having some major issues with my 2008 lt 4x4 Tahoe not z71 edition all stock 126k so heres the deal one day it was fine the next morning service 4 wheel drive , service tire moniter, service traction , blinkers don't work , brake lights don't work , key fob and door...

My 06 Tahoe (5.3) has some weird issues... started by going into "reduced engine power" mode several times... I put in a new battery, seemed to solve problem, but now the electric locks all activate randomly while driving, airbag and engine lights go on and off randomly and air conditioning...

Does anyone know how to deactivate the feature which requires the vehicle to be in park before unlocking the rear doors in a 2008 Tahoe? This vehicle is being used as a service vehicle, and individuals need to be able to quickly enter and exit the rear doors while the vehicle is in gear.
