My air conditioner blows hot air only, actually blows hot air all the time.

Hot air holds more moisture than cold air so if you cool moist air the water will condense out and become dryer. Your "dehumidifier" is actually the car's air conditioner.

If you have a viscous fan hub have it replaced as it is not working. The problem you have is that the engine is not driving the fan to draw air through the radiator when idling so the engine overheats . When moving the air flow from driving cools the radiator and so the temp goes back down. If you have electric fans have the codes read to find the fault or check why the electric fans are not working.

Could be a list of things including low on freon, low pressure switch, relay, or the a/c clutch on the compressor.
