My 2004 2500HD has been rock solid since new…until it died last month. 6.0L, automatic, 4X4, 160K. Idling in line at Walgreens and it flashed a bunch of idiot lights and the AC and radio quit. A few minutes later it started and ran fine to go home but would not crank once home. Serpentine belt is good. No alternator light but battery suggested I drove home without an alternator. Replaced the battery and it made no difference. Towed to shop. Shop billed a months’ retirement and said they replaced the PCB, whatever that is. Made one trip to town and it died three times in traffic in under 10 miles. Towed again! Mechanic has had it two weeks and cannot diagnose the cause. I’m going to have to have it towed somewhere else now.
Any of you ever seen this? I could sure use some guidance.
