2002 avy 1500 z71. Heading down the road today with a/c and cruise control on when out of know where the cruise control and a/c shut off at the exact same time as the battery warning light came on. Now I have no power to my 4x4 switches, my fan, cruise control, and gas, temp and gauge cluster lights are not working. Also have no gear readout(PRND321). any thoughts?
