Reminds me of the dash fix for Tahoe's, 'burbs, and D-maxes - the gauge needles would go all haywire, not swipe at all, or halfway, or stick. For those dashes with the 8 gauge needles, what a PITA.
Turns out for $30 or so you could order all 8 of the little stepper motors that drive the gauge needles and unsolder them out of the PC board inside the dash and replace them all. Full instructions on disassembling the dash, removing the PC board, soldering the motors and calibrating them. A job that a pro-shop would charge several hundred dollars for. I did mine on a '04 Duramax crew and it wasn't that hard. Nice time to replace any failed LED indicator lamps in the same board. I had just a couple.
Funniest part was that the motors were made by Swatch - you know, the watch people?!
Or the BMW 3-series temp control module - fan motor would go all over the place, up and down, shut off, or full speed, just out of control. A $800 fix at the dealer - it was a $100 part up under the dash that was hard to get to. With step by step it wasn't that tough to do, fixed it!
Love the owners forums!
