Tahoe V8 C&K 100K. Car had been working fine, one day going to school it got hot and the Temp Gauge pegged. Checked the water pump, cleaned radiator out and replaced the thermostat and ECT sender. Resistance seems to change OK on the ECT (checked unplugged) as engine warms up, but NO indication on the gauge in the instrument panel. When you crank over the car on initial start, the gauge will peg, then drop to lowest position and sit there.
Went to the library and the electrical diagram shows a connection from the sender to the TP, but don't
know how they interact. How could I check?
Any chance we blitzed the VCM with the once hot temperature? Would appreciate your help as I have to use my parents car to get to school until I can get my Blazer running.
