Hey folks, this is an awkward way on to introduce myself to the forum but it's as good as any! I just got rid of a 1997 F(found) O(on) R(roadside) D(dead) F-150 P.O.S. that wasn't worth another minute of my time! I've always been a Chevy truck guy, and as of today I'm back in the saddle with a used 2006 Silverado 1500, extended cab, 5.3L Vortec with right at 125K miles, in excellent condition that I picked up on Craigslist for a very good price! A small power steering fluid leak, and bringing the stereo up to date with Bluetooth are the biggest issues I can find at the moment, but the tachometer being inop is something I'd hope I could get a clue from someone here with. The previous owner said he was told it could be a bad solder joint on the instrument panel. Has anyone seen or heard of this before or have any solid repair for this? Any help would be greatly appreciated!
