you need a new control unit.
That is not always true. Check your codes on your control unit by pressing the Off button and floor bottom at the same time. Thsi will bring up your code or codes if any thing is wrong. (It takes about 30 seconds). Its sounds like your plenum door is stuck or the motor that controls it is faulty. Codes are 24 and 25. The next step would be to replace the plenum motor that controls the plenum door. Sorry to say this but its located under the dash which needs to be removed. Its about a 4 hour job for a novice and you will need instructions. Wish I could be more help.

Also, It doesn't matter if it is on defrost, heat, vent or whatever. It never overheats until you turn the thermostat control to hot. Then the gauge goes up. You turn it back to cold and it goes back down. I checked the heater core and thermostat. Any ideas? Thats a strange one. Heater settings should not make a difference in the operating temperature of the engine unless some kind of electrical malfunction is preventing the radiator cooling fan from coming on when the temp is set to hot. Check to see that the fan is running when the heat is on and maybe you will have a place to start troubleshooting the problem.
Remove the center console remove the floor vent remove the heater core cover the heater core is right under the climate control unit remove the two screws that hold the heater core in place, open the hood and remove the heater hose from the heater core lines, now go inside and pull out the old heater core you don't have to remove the whole dash just the front of it
Bad vac line or cable to your vent controls. There is a door to your heater core that is supposed to closed when ac is on-yours is not. A place that does ac repairs can check it out for you.
There are several types but generally the best are either the in-line heater hose style or the freeze plug style. If you use the in-line heater hose style, just cut the heater hose, put the block heater in place then make sure the heater control is left on at night. If you use the freeze plug style you'll need to remove an existing freeze plug and put the block heater in it's place. The magnetic style block heaters are not recommended. They seem like a good idea but they're more trouble than they're worth.
Most thermocouples are held in place at the pilot light by pushing them into a clip that grabs it on both sides. The control end is held in place by a nut that the shaft of the thermocouple goes through.
Place a white towel on the floor of the car if when you press it down on there and the liquid is green its coolant leaking into your car it could be coming from a hose or your heater core
Unless there is something unusual about your specific model, the only place you would have coolant inside the passenger cab is in the heater core. The quickest check would be to connect the two heater hoses together inside the enngine compartment to bypass the heater core all together. If the leak stops you need to replace or repair the heater core.
