yeah it sounds like your engine fan is not working. you have two fans in your car one that turns on when your engine starts and one that truns on when you turn on your ac. now if your engine temp drops when you trun your ac on it's because the ac fan is cooling the radiator(the reason that your car cools down when you are driving is because the air is cooling the radiator). just check to see if the engine fan is blowing when you start the car with the ac off, if there is no fan going then you need to figure out why it is not turning on.

Also, make sure that your thermostat is working properly. Really no way to tell, except to replace the thermostat and drain your radiator. Refill then go drive. If it still get's hot sitting still, then it's the fan switch like P10 WRC had stated. Might be a bad relay, etc.
