Cooling Fan 2 (A/C Fan) not blowing

The problem could be in the ignition switch itself.

CHECK THE THERMOSTAT. THERMOSTAT IS THE ONE THAT SENSE THE ENGINE TEMPERATURE AND TURNS ON COOLING FAN WHEN THE ENGINE IS HOT.

If your car is equipped with a 3.1 or a 3.4 litre V6 and you have preformed all of the above listed work then I would have to say its the intake manifold gaskets. They commonly blow on these motors. Just a design flaw, nothing but replacing them when they leak can fix this. Also run a coolant pressure test on the system to check for minor things like a leak that you cant see from visual inspection. Hope this helps.

Okay, here are a few possibilities. First, they do make a High performance freon and carry it at Autoparts stores. Second, moderation. All A/C systems have a low pressure cutoff switch and a high pressure cutoff switch. You want to stay below the high limit. Freon is a gas and will generate more pressure when the outside air is hotter. The switches run $20 to $40 each. It may be possible to change to different pressure numbers without blowing a hose. You old switches could be weak.

Hello, as previously suggested by my collegue it appears you have an air lock. Have you tried parking the vehicle on level ground, from cold with radiator cap off start the car and leave it idling. Make sure the fluid/coolant levels are o.k. and let the engine reach operating temp. Keep some warm water handy and watch/listen the water/coolant system (Keep a safe/sensible distance from radiator) hopefully after a while the system will bubble and boil up let it settle for a few seconds and then top up with very warm water do this until it hopefully stops belching out of radiator. Replace cap and hopefully top and bottom hoses will be warm. Oh! nearly forgot keep all heater controls on hot with blower on full..(Inside the vehicle)
Finally I'm not joshing but is the thermostat in the right way round and functioning correctly? to test drop it in some boiling water it should open almost immeadiatly.
sorry for the epic but I'm here to help and hopefully save you time and money.
Good luck and a Happy New Year to you and your family!
