When I drive the air flow keeps the temp down.

An air conditioner works by removing heat from the passenger compartment and releasing it to the outside atmosphere via the condenser located in front of your radiator. This additional heat is then pulled through your radiator fins.
So, at an idle , the heat from the a/c is in the air your radiator uses to cool itself. Your cooling system for your engine is not working correctly causing it to overheat.
Some common causes of overheating:
Timing is off
Bad, loose or wrong radiator cap
Improper mixture of antifreeze
Poor tune up condition
Bad switch if electric cooling fan
Bad fan clutch if it has one
Damaged fan blades
OEM cooling shroud damaged or missing
Clogged or undersized radiator
Damaged radiator
Slipping water pump belt
Sticking thermostat
Leaking t-stat housing
Remember that for every pound of pressure your cooling system has, the boiling point of your antifreeze mixture rises, so if you have a small leak or the wrong cap, you may not reach the required pressure to cool it.

Pop your hood and see if your electric radiator fan is coming on. I had this happen once and discovered the fan motor had stopped working.
Normally, the fan motor kicks on, especially when using the AC and helps the flow of air through the radiator to keep the engine temp down. Also check to see if there are any obstructions at your grill or at the front of the radiator.

The thermostat is the most basic clarification why it would overheat. its in many circumstances positioned at the front of the engine bay, hint the hose from the rad to the the engine and it will be in there. eliminate it and position it right into a pan of water and placed it on the range. reveal screen the water temp and it would open at about 195 F or ninety oC. If it really is operating then the mission will be a blockage. jack the front of the motorcar up and bleed the radiator at its optimal element to substantiate there is not any air interior. good luck

Depends on the car. The electric fan automatically comes on when the AC is on but it may not be enough to keep your car cool. A small rise is normal but it it inches toward the red zone you need to get it checked out. You may just be low on coolant or there may be debris clogging your radiator. Take it in and get it diagnosed.

If your car has an electric cooling fan (almost all new cars do), it may not be switching on. It should come on when the A/C is on or when the coolant reaches a certain temperature.
Check the fan.

Replace the radiator cap and see if that helps.
