fan does not generally come on till you reach about 210f. second fay comes on when ac compressor is on. Allowing for gauge inaccuracy this does not sound like a problem. Have you checked for coolant loss inside or outside the engine? If coolant is low, it may not be reaching the sensor unless you make pump run faster. Those engines are known for head and intake gasket problems, which may be the underlying cause of what you described. A partilally obstructed radiator can give some of the symptoms but I don't thind that is it.

If you have an electric display ATC type control there is a blower switch which controls only the blower whether its on heat or cool. On my Ford system it was under the hood in the duct work on the opposite end of the blower. Your system is probably electronic and if you replace this part it may work, mine did. You might want to go to a salvage yard and reclaim one from a wreck. You will learn where the part is and how hard it is to remove before you work on your car.
