so glad I found the forum here
My Dad passed away and I got this nice vehicle when he did. Never had an electronic dash,etc.
He took real good care of it, babied it. Second week I drove it, dash suddenly went black, never came back. Also at same time, the mileagemeter scans quickly thru all numbers it could possibly display, whether idling or driving, is never static anymore, accumulating miles driven. Went for four mechanics, all said common problem with Chev Blazers,electronic dash, all say about $1500 and used parts (hopefully working) from junk yards.
