The radiator you may be talking about is the one at the front of the car but there is also a radiator under the heater control switches which is the radiator for the heating,that is the one that is probably air-locked,you DON'T have to touch the inside of the car console to remedy it,if your Main radiator is hot when the car has warmed up(hot top and bottom like a house radiator)the air lock is in the heater MATRIX which is a posh name for the radiator inside the car,any mechanic worth his salt should be able to disconnect the heater hose fill it with water and solve your problem for you easy peasy.
