Air conditioning puts an extra load on the engine. It often shows up a restriction in the radiator that isn't a problem when the engine is not under the additional load of having to drive and air conditioning compressor. Do you hear the air conditioning condenser fan run when you turn on and off the air conditioning? I will send you an article I wrote about cooling systems and particular problems, you have made me think I need to add to the article the effects air conditioning has on a cooling system.

Mine was doing the same thing and it was the AC fan not coming on! All I needed was a fuse :D
