91 Blazer Instrument Panel

[revmatty]

I recently bought a 91 Blazer S-10 from the mechanic of a trucking company I work for. The only instruments that work on the dash are my fuel, voltometer, water temp.

The oil, speedo(the most important, that I want to work), gear indicator, don't work. From the looks of the dash it looks like a mechanical system, with the big orange needles. When I asked him about it he said they worked fine when he dropped it off , he suggested the fuses. I pulled everyone out and checked them with a multimeter. Never found one for the gauges.

Just recently now I lost all the dash lights, except for the a/c / heater lights.

There was a snow storm the weekend I got the truck, so possiblity of snow getting up and under and loosening or removing a gound wire? If this is the case, I have no idea where to start.

I have thought of just going to the NAPA (my boss owns, besides the trucking company), and buying a elctric speedo, but then again, I'm not an auto mechanicaly in tune guy

Also, if anyone has a wirring diagram for the car streo, since it was stollen I would apreiciate it.

Thanks all and have a Merry and Safe Christmas!!
