Temp guage not working prpert. Stays on H even with car off.
Noticed problem with guage last summer. Put on diagnostic, car temp is not indicating overheating. Changed sending unit & temp sensor already. Drove in water 2 days ago and temp guage fell all the way to or past H. not moving at all. Please help!!

You might want to chk. the connection on the sending unit and temp. sensor thats the way they act when they loose a connection. If that chk. out ok then it would have to be the guage its self thats faulty.

this may be a goofy question BUT do you mean flushed the radiator not the heater core. Heater core is on the firewall.
Check the hoses going into the heater core to be sure they are both hot after the car has reached running temp. This will let you know if you have a blocked heater core not radiator.
gear position indicator will start blinking a code(?) You may think it's blinking a code , but it's not . Doesn't have the capability to do that .
Traction, security light on - take it and have DTC'S - diagnostic trouble codes checked . Sounds like you have insturment cluster problem , Without testing anything that would be a guess . Take it to a qualifieed repair shop an have it diagnosed .
YOur guage is faulty. Your will need to replace your guage if it stays in the hot position even when your car is off and your key is out of the ignition. If it only rises to hot when you turn the key to the run position, you have a wire between your guage and your temp sending unit that has been gounded out. Usually this happens when a person opens their hood to add oil or perform some minor maintenance on the engine and inadvertantly bumps the sensor or switch or wiring. This causes about 65% of these minor issues people incur, but if it does stay all the way up with your key out of the ignition switch, then you will need to replace your temp guage.
Sounds like a faulty sensor, if the actual temp is 195/215. The ICM is processing the information it receives from the sensor and performs accordingly. A complete diagnostic scan would be helpful in determining the proper repairs needed to correct the problem. Good luck...i hope this helps, please rate me a fixya.
seems high to me. summer thermostats open at 185 , winter thermostats open at 195. At highway speeds , there should be more than enough air flow through the radiator to keep engine in the normal range. Your radiator might be pluged up and cooling poorly , but I suspect your temp guage might be inacurate.
When this happens have you noticed what temp guage said? if it was hot then you might try a lower temperature thermostat and flush coolant system.If it doesn't actualy get hot coolant wise then a vapor lock in fuel system would be unlikely to my knowledge, car has fuel pump in gas tank and is fuel injected.If you only take short trips in car cooling system,<thermostat,water pump,coolant level and radiator> could be at fault and only when running for longer periods of time might cause overheating and not noticed on regular days on short trips.
