Question about 1993 Pontiac Grand Am
Also, with the scanner removed and a jumper between terminal a and b, the fan will run. What is wrong? Fan does not operate under normal driving conditions. The temperature sensor, fan relay, thermostat, radiator, water pump all have been replaced. Along with timing chain, head gasket. When driving the dash temperature gauge runs to hot but even when the ignition is off the temperature gauge shows 200 degrees, does not return to zero.
Problem with dash board. Bad contact. Reconect all conector and conect again...

If electric fans are coming on, and you have filled the system with the heater turned on high to purge it of air, even though you flushed it, I'd have the radiator flow tested (even when flushing, coolant tends to go around internal blockages, limiting its ability to work correctly) otherwise you need to begin testing from square one like you had never seen it before (don;'t assume anything you did is working) Pressure testing of coolant system, hydrocarbon test at fill opening and engine compression tests are important as well as what I mentioned above.

What's chances that the temperature gauge or sender itself is wrong?
Is the heat exceptionally hot? What temperature is the heater dicharge when the gauge reads 260?
I think that the sender is not expensive, try that. An auto parts store could get you an inexpensive dial gauge that you might be able to install in place of the sender.
