Why does the heater blow cold


Could be a number of things from maladjusted air flaps, faulty servo motors, faulty climate control to a partially blocked heater matrix.

More clues are needed. The first step would be to ensure the engine is reaching full operating temperature and the hot coolant is circulating through the heater.

Erratic or intermittent heater operation can be an early sign of head gasket failure. It is easy to jump to false conclusions so I suggest getting some experienced help.

Instruments not working on 1997 Jimmy, after replaceing the heater core


Check, you may have a connection to the cluster not fully plugged in. It's got to be at the cluster-the instrument panel.

Guages not working,


If all voltages checked ok,then most probably its faulty instrument cluster board on which gauges are connected.Yes if cluster circuit board looks ok,then also it can be faulty.Somewhere there is minute short or burn on board then such prolem arises.
Also check the fuse box.One under hood and other under dash.Inspect each and every fuse and see if all are fine or not.

Gas gauge jumping around


Gas gauge jumping around usually implies fuel level sensor in tank is going bad...Usually if the gauge in dash is going bad will read empty or at various positions depending on fuel level in tank..Electrical short problem in gauge usually affects other gauges in cluster
