My brother has a 99 chevy silverado new style 1/2 ton with push button 4x4. Yesterday, all the lights in the push button switched flashed, then they all went out, now the 4 wheel drive wont engage. THere was no grinding noise at all, just silence. I replaced the push button switch($50), and nothing. What next, or am I gonna have to take this electinically controlled pile to the steeler to have it checked out? Any info would be greatly appreciated. THank!
p.s. I checked the fuses and they were good.
