Why is my Mercury Grand Marquis blowing hot air?
When the air conditioner in your 2009 Mercury Grand Marquis starts blowing hot air, you likely have a freon leak. Recharging the freon in your AC system is an inexpensive and easy first step to restoring the cooling capacity of your A/C system.
How is the heat in a Grand Marquis controlled?
With the engine at full operating temperature, locate the two heater hoses where they go into the firewall and feel them to see if they are both hot to the touch. If they are both hot, the heat in that vehicle is controlled by a blend door that regulates heated air flow. It is operated by an electric motor/actuator.
Can you add Freon to a Grand Marquis?
The A/C system in your Grand Marquis consists of a compressor that is belt-driven, an evaporator and freon. If there is a problem with your compressor or evaporator, adding freon will not restore cooling. How to add freon to your 2009 Mercury Grand Marquis: hook up the can of refrigerant (likely r-134a) to the low pressure port.
Is the a / C blowing out hot air?
