Air Conditioning problem on 2001 Mercury Grand Marquis
When the A/C is on and blowing cold air, it suddenly changes to blowing warm air. It is full of freon.
sound like improper refrigerant flow...could be overcharges too---but have some service done...have them put in a new filter/drier and it'll come back into service~
I was told that it might be the blend door actuator.
that'd be convenient~ check your fuses...
here's YOUR buggy~
the fuses...perhaps this time we can see which fuse is blown...and why it is blown~
I'm going to say look at fuse 2-23 because this one is environmental~
